The big bang spewed a bunch of "stuff"(hydrogen and helium, mostly) out into the universe. This stuff continues to expand away from where the Big Bang was. The stuff formed stars, which were very short-lived. These early stars made heavier elements that other stars used to live longer.
When some stars were at the end of their life, they imploded into a Black Hole. Black Holes have a lot of gravity around them, so other stars orbited them. These orbits turned into galaxies. Every galaxy, including ours, has a Black Hole at the center of it.
Out at the edge of the Milky Way, on one of the spiral's arms is where the Sun was created. It was created from gas that was pulled together over many millions of years. After the gas reached a certain density, it started to undergo Fusion(a way of creating energy). It created heavy elements that it pushed into what is the solar system.
The Earth and all the other planets were created from bits of rock that were pulled together due to gravity.
Humans evolved from single-celled organisms, just like everything else. In the past we were something like apes, though not exactly the same. Everything evolves at the same pace, our "ancestors" don't exist any more, because they evolved into us.
orphans answered Saturday July 14 2007, 12:50 pm: Science believe that our universe collided with another universe, and that created life. Yes, scientist do still believe we came from apes. The theory of evolution says that we all came from little bacteria and have evolved over the past billions of years.
