What is the big bang and how did it happen?
Also do you think that 1 billion miles away or something like that, that there is another solar system and other lifeforms?
Bonus: How is the universe everlasting and if its not how does it end?

The Big Bang was the beginning of the Universe. The Universe started out the size of a proton and then began expanding rapidly. Here are two good sites: http://liftoff.msfc.nasa.gov/academy/universe/b_bang.html
http://map.gsfc.nasa.gov/m_uni/uni_101bb1.html
There are other solar systems out there and some even have planets with life on them. The Universe is far too big to only have one insignificant planet with life on it. And the solar system extends for at least 8 billion miles beyond the Sun.

The Universe will keep expanding for billions of years. Eventually, there will come a time when protons and neutrons will break down and absolute zero (0 K) is reached. This will be the end of the Universe.

From the link below :
"One of the most persistently asked questions has been: How was the universe created? Many once believed that the universe had no beginning or end and was truly infinite. Through the inception of the Big Bang theory, however,no longer could the universe be considered infinite. The universe was forced to take on the properties of a finite phenomenon, possessing a history and a beginning.
About 15 billion years ago a tremendous explosion started the expansion of the universe. This explosion is known as the Big Bang. At the point of this event all of the matter and energy of space was contained at one point. What exisisted prior to this event is completely unknown and is a matter of pure speculation. This occurance was not a conventional explosion but rather an event filling all of space with all of the particles of the embryonic universe rushing away from each other. The Big Bang actually consisted of an explosion of space within itself unlike an explosion of a bomb were fragments are thrown outward. The galaxies were not all clumped together, but rather the Big Bang lay the foundations for the universe."
There are definitely other solar systems in the universe, as other planets have been detected revolving around their own suns.
As to whether there are other life-forms. Well, as the universe is, almost to all intents and purposes, infinite as it is so huge then, statistically it is almost a certainty that other life-forms exist.
There are two theories as to the end of the universe. One suggests that gravity will eventually slow down the expansion and gradually pull all the universe back to a single point again (known as the "Big Crunch"). The other suggests that the universe will continue to expand infinitely and, as all bodies move away from each other, the night sky will eventually become starless.

A billion miles isn't that far in space. That only takes you to about Saturn
To give you an idea how short a distance that is, Saturn is about 10 AU (Astronomical Units) away from us. The nearest star is 267113 AU away, and that's just the nearest one. That's about 24,841,525,275,000 miles away.
We've already found several other solar systems, one has at least five planets (but we can only detect the biggest ones, it could have many more smaller ones)

the big bang theory is that billions and billions of years ago there was a little speck of life form and all of a sudden it exploded and there was the solar system and it came along with a really loud noise that scientists say can still be heard lightyears away from here. Yes i do think there is more life form other than earth. The universe is not everlasting the core inthe earth will eventually burn out and so will the sun just like stars but the burn out sooner because they are smaller so the sun will not burn out in our life time.

Ther e must hav e been one bang per Solar star system.
The Universe will pass away . That means it is decaying with time. Mass becomes entropy.
Therefore there needs to be a rescue.
