I saw a fantastic programme called "the day earth began" wich isn't avaiulable on dvd i've spent 3 years l;ooking for it but apparantly the discovery channel play it now and again.

The Big Bang created the Universe; as a consequence of that creation, the Earth & our solar system developed. The Big Bang isn't directly responsible for any affects to climate and life here on Earth, but the materials USED to create climate & life are from the Big Bang...

The big bang is a theory of the creation of the whole universe and not just our world, which is planet Earth. The Earth did not come to exist for a very long time after the big bang. It formed much later in a separate sequence of events in one very small corner of the universe. For purposes of climate and life, we can safely ignore the rest of the universe and consider the Sun and Earth as a separate system, the solar system, independent of the universe in most respects. To think of the world (as in planet Earth) in the same way as the whole universe is to show a profound underestimation of the size of the universe. Planet Earth is to the universe as less than one drop of water is to the oceans. But you cannot really imagine how big the universe is with comparisons like drops and oceans because drops are too big and oceans WAY WAY too small. To get some idea of how large the universe is, just look at the stars at night, how small and dim they are, and know that each one is actually a Sun, like the one that makes you wear sunglasses in the daytime, and only seem dim because they are so far away. How much farther away would the Sun have to be to look that dim? It boggles the mind, but that is still nothing compared to the whole universe, because for every star you can see with your eye there are billions more that are too far away to see at all unless you use a telescope. And each one is actually like the Sun, incredibly big and bright

The Big Bang was the creation of the Universe, not the world. Earth came much later.

The universe is an estimated 13.6 billion years old. The earth is about 4.57 billion years old, the Sun slightly more than that.
A very young Sun in its very early days ejected the gaseous material which then cooled, from which the planets then formed.
Therefore about 9 billion years (two-thirds of the Universe's life-to-date) elapsed before the earth and the other planets on the Solar System came into being.
So the Big Bang did not create the world, it merely created the matter from which all stars and all worlds, of various ages, would later form.

Today, we know most of the things happened AFTER Big Bang..
At the big bang itself, the universe is thought to have had zero size, and so to have been infinitely hot. But as the universe expanded, the temperature of the radiation decreased. One second after the big bang, it would have fallen to about ten thousand million degrees. This is about thousand times the temperature at the center of the sun, but temperatures as high as this are reached in h-bomb explosions. At this time, universe must have contained photons, electrons and neutrons. About 100 seconds after big bang, the temperature would have fallen to 1000 million degrees. At this temperature, protons and neutrons would no longer have energy to escape the strong nuclear force, and would have combined to form deutrium. Within only a few hours of the big-bang, production of helium would have stopped for next million years or so...the universe just expanded during this period. The universe as a whole would have continued expanding and cooling, but in the regions that were slightly denser than average, the expansion would have been slowed down by extra graviational attraction. This would eventually stopped expansion in some areas and cause them to start recollapse. As they were collapsing, gravitational pull of matter outside these regions might start them rotating which resulted in the formation of galaxies. As the time went on, the H and He gas in the galaxies would break up into smaller clouds that would collapse under their own gravity. As these contracted, and the atoms within them collided with one another, the temperatures of gas would increase, until eventually it became hot enough to start nuclear fusion reactions and this resulted in formation of stars like our sun. Our sun is a second or third generation star, formed some five thousand million years ago out of a cloud of rotating gas containing the debris of earlier supernovas. Most of the gas in that cloud went to form the sun or got blown away, but a small amount of heavier elements collected together to form the bodies that now orbit the sun as planets like the earth.

The "Big Bang" is a theory for how the Universe may have begun. To date it is the most useful and logical explanation and much astronomical evidence points to it. I think you are confusing the world (the earth) with the universe.

A big bang creates everything from nothing.
Which goes against the basic:
No thing comes from nothing.
and
No thing goes to nothing.
Big bang is fine as iit is one of a series of events. Mass collecting into one location over a long period of time could become massive enough to explode into the items we currently observe and in the patern of Galaxies as we see them to be.
If there is one big bang then there could be others.
As soon as a sequence of events occure then the propability of a simular sequence of happening greatly increases.
The earth and the solar system is material
released from the Milky Way galactic core.
A change of state of some of the material in the galactic core caused material to split into dencer material and less dence material.
The less dence material rose like a bubble bumping into alot of other material of lessining density, to the surface of the Galactic core and exited the central mass in a almost strait line trajectory. I see our earth sun and planets all leaving our galactic core at once. Our large elements were part of the initial bubble deep within the Galactic core. We picked up the smaller elements as we passed through the upper layers of the Galactic core. We as the bubble are made up of about the same material of the rest of our solar system.

I think for our very existance, we must thank the big bang.
Lets see cronologically, what seems to have happened..
b4 d big bang took place, the universe was anti matter assumed 2 b of the size of 1 billionth of a proton.
Now that xploded like hell, which itself is the Big Bang.
This explosion emmited a huge number of electrons(hydrogen atoms).
due to the extremely high temperature, fusion took place and helium was formed.
And unbelievably, this blast was of such unimaginable magnitude, that it is said that 98% of the universe was formed in the 1st 3mins after the Bang.
now higher elements were formed due to explosion of stars which emitted tremendous amt of light and heat causing fusion of the elements present in the core of the star. These are by the way called super novae.
this slowly resulted in gases, which started 2 form the environment.
then 4.6 billion years ago, the sun(younger then) got mad and threw lot of crap from its surface, which incidentally was solid.These particles started forming spheres and our solar system was ready.
Then, the earths atmosphere contributed of CO2, methane and other gases(harmful for us). Slowly things changed, and due to perfect proporion of elements and gravity, our atmosphere was started 2 b made.
and then came the first creature 2 live.
An atom put 2 live.A cell made to move.
And after a lot of crappy stuff in the middle, we came 2 existance..
So thus, everything from the big bang has favoured a life. One tiniest change in gases, one tiniest change in gravity and we are all dead.
Its amazing
Its unbelievable
