This is actually two questions since life began (at least on Earth) about 10 billion years after the universe began.
In talking about the beginning of the universe, a great deal of care is needed because time itself is part of the universe so even talking about 'before the universe' is problematic. We know that the universe has been undergoing an expansion that, if projected backwards, started about 13.7 billion years ago. We also understand a great deal of how the basic elements have formed since that beginning. What we don't know is whether it makes sense to talk about a time before the universe or to talk about a 'cause' of the universe. Remember that the term 'cause' is also tied up with the notion of time, which (again) is part of the universe.
Life, on the other hand, started on earth about 3.8 billion years ago. The Earth and Sun formed from the collapse of an interstellar cloud, much like we see happening in the Eagle nebula today. Life formed after the Earth cooled enough to support liquid water (as opposed to steam) and was originally bacterial. We do not know the exact mechanisms involved, mostly because the evidence has been eroded in the time since it happened. However, we know a great deal about the chemistry of life and that hydrothermal vents and periods of drying and heating were probably crucial for the start of life. The crucial questions are how a mix of amino and nucleic acids attained enough catalytic activity to form stable cycles of chemistry.
The hypothesis of a deity is not needed to explain these things. If anything, it gets in the way of true understanding and the search for truth.

Yes, according to religious nut cases "god in the beginning created the heavens and the earth", science has shown that the age of the universe is 13.7 billion years, age of the earth about 4.6 billion, so if you consider a 9 billion year difference "the beginning" then the bible is right, lol. And apparently nothing else exists in the universe besides our solar system, which just happens to revolve about the earth, according to the bible.
Now for the real answer, the universe and everything in it started out after a "big bang", where the energy that was confined to a singularity was transformed into quarks, leptons, and eventually the elements and basically the laws of physics as we know them were born. This is really the answer in a nutshell. You can read this about the big bang
http://en.wikipedia.org/wiki/Big_bang
As far as planets and stars forming, they all go through the same process. Planets and other stars are formed from the remains of dead stars, a process that takes millions of years.

This is such a common question but such an important one it has to be answered each time. When a man named Hubble discovered that the galaxies were moving away from each other if was the piece of evidence that confirmed the theory of the big bang. Everything in existance today came into existance at that time about fifteen billion years ago. From the void a point smaller than an atom there appeared all of the energy that exists today, the temperature suddenly rose from absolute zero to billions of degrees, in this maelstrom particles of matter condensed from the energy, they were the particles that would make up all that is in the entire universe today. It may seem hard to believe but everything that exists is made of only the same three particles, the proton, the neutron and the electron. The simplest element is hydrogen, a gas, it formed great clouds that were millions of light years across, these clouds condensed and compressed because of gravity into neuclear furnaces called stars. These stars manufactured all the different elements that make up what is called the periodic table, all of these elements are made of the three particles, the proton,the neutron and the electron, and every atom in your body was made inside a star. Over the course of billions of years planets formed and orbited these stars, one ot those stars is our sun and one of those planets is Earth. The sun provided everything that was needed for the begining of life on Earth and through a process called evolution humans came into being. As we age we try to learn all we can about the universe and what is going to happen to it. As of now scientists are unsure, they need more information to be able to determine if the universe will go on expanding or slow it's expansion down and begin to collapse inward into a big crunch. Our beautiful planet complete with it's atmosphere speeds through space at 66,000 MPH as it travels around the giver of all life, our star, the sun and it has been doing this for eight billion yerars, Fantastic, is it not?

Well the only place in the universe that we are 100% certain that there is any kind of life is earth at the moment. There are theories about microbes on Titan, or on the surface of Mars, but none have been collected, or confirmed.
So to me the question would have to be: "How did life on earth start?"
The answer to that may or maynot be related to astronomy. The main theory related to astronony is Panspermia. This theory says that microscopic life was probably carried here by meteors and caused all kinds of forms to develop and evolve over time, leading to us. I personally don't buy this theory as the odds of it happening are remote at best, but that's the best answer I can offer to the question in the context of astronomy.
The truth is that there are a world full of theories but, we just don't know which if any are right. Don't let the people who say that God did it convince you, because they are as clueless as the rest of us. There is even less evidence to support intelligent design than any scientific idea you might want to name. Not to mention that its just so arrogant to assume that your God made the entire universe when there are all different faiths out there, and not just Christianity.
Also notice how many people answered your question with the Big Bang theory. This is the widely accepted idea of the origins of the universe. Not life here on earth. Those two are not necessarily one and the same.

The most prevalant theory for the creation of the universe is called "The Big Bang." It says that, approximately 13.7 billion years ago, from a point smaller than an atom, known as a singularity, the entire universe exploded into existence and then quickly expanded (and continues to expand). The question about what was before the big bang, is currently a philosophical and not a scientific one.
As far as the origins of life, scientists believe that long ago there was a soupy mixture of proteins and amino acids in a much different atmosphere than we have now, which, perhaps with the help of electric current, eventually formed living organisms. These organisms, over hundreds of millions of years, continued to adapt to their surroundings by evolving into more complex forms, and eventually into all the living species which have existed on the Earth.
As we become more advanced in our knowledge, we will have a better understanding as to the science behind these questions.

scientifically, here is some notes and info on the big bang, where the universe was created.
There are many different theories people have thought up of for the creation of the universe:
ex: always there, came from nothingness, and more. Big bang= the most plausible theory.
What is the big bang?- the theory that says the universe began with a huge explosion about 13.7 billion years ago.
How do we know this? Universal expansion. Scientists have realized that the galaxies are moving apart. Scientists have also observed that it looks life all the galaxies are moving away from us. Does this mean we’re the center of the universe, or does it mean that aliens have seen the way we are destroying earth and want to get away as far as possible? As much as I like the second idea, neither are correct. To any galaxy you go to, if you observe, you will see all the galaxies moving away from you, as if you were the center.
A good example is the following-
Steps– 1. Draw dots on uninflated balloon.
2. Inflate, observe that each dot evenly retreat from each other. Each “galaxy” sees the same thing, galaxies moving away from them. There is no center, nor edge. The balloon surface is a 2d model of a 3d universe.
Now... how is the universe expanding? What is it like when its expanding? Well, it’s safe to say that the big bang is still happening. The universe is still expanding through the big bang, for on the outermost section of the universe, the terrific explosion is still occurring, forming our universe.
There are 6 layers of the universe- the furthest- big bang. 2nd furthest- radiation era. 3rd furthest- galaxies are forming. 4th furthest, there are many intergalactic clouds. The most distant quasars are here.
4th furthest- active galaxies, radio galaxies, and quasars are here. Now, our layer- a wall of galaxies, galaxy clusters, the Virgo Cluster, M31, and the Local Group.
“Glossary”- quasars- most distant known objects in the universe, the dazzling energetic cores of colliding galaxies, 12-14 billion light years from earth.
M31- Andromeda Galaxy
Radiation Era- begins 2-3 minutes to 300,000 years after the big bang- where space cooled enough for protons, neutrons, and elections to combine to form atoms. Now light and other formations can flow thru space without being absorbed by subatomic particles. The radiation still moves through space today, though weak.
If the universe is expanding, what is it expanding into?- try to avoid thinking of big bang as explosion, like its going into something. It wasn’t and explosion into space. It was a simultaneous creation and expansion OF space. Everything is inside. There is no understandable/perceivable outside.
What came before the big bang? Well, science implies that our universe is not the only one. We may be a speck in an infinite universe of universes w/ no beginning or end. The few billionths of seconds before the big bang, there was nothingness. Nothingness- an infinite vacuum- quantum fluctuation- virtual particles- “dance” into existence only to vanish back into the froth of the vacuum an instant later. Scientists think this happens in and out of our universe. I think the big bang happened because the vacuum sucked out on our tiny “universe molecule” and forced it to “explode” and create our universe. (But that’s just my opinion)

at the beginning, the sunlight won't explode. it will develop to grow to be a purple great, and then fall down to grow to be a white dwarf. in this technique, the interior planets would be destroyed. At no element will our sunlight grow to be a supernova, or perhaps an effortless nova. that is in easy terms too small. It follows from this that it can not grow to be a black hollow, the two. The Universe will proceed long, long after our sunlight and the Earth disappear, and probably by utilizing then mankind could have opened up in the time of the Universe, and our previous domicile would be in easy terms a memory.

I will put my effort to answere you. God was not created He was already there. So, God created the plants, human beings the sun and the stars they sky and the moon and all they living being. i could say people started to find how all this happened and tried to give reasons which we call it science.?Did you ever tried to find out why did they give it that name there could another name which suited better. I wonder why did they call it science? One scientist come and discover one thing says the causes for it etc., another comes and redifine it. God is the creator of life.
