As far as we understand, our universe, and therefore anything in it, did not exist until the Big Bang created it, so black holes couldn't have existed in our universe until after our universe had been created.

I'm actually beginning to think that time may have existed before the Big Bang, but was simply not relevant or applicable to our universe until our universe was created i.e. it couldn't apply to something that didn't exist.  If so, then time, being to tightly bound to space (and visa-versa), at least from our point of view, would have appeared to start at the same time as space.

as i know about big bang,it is said that a wondering star came nearer to sun and pull its tidal waves on its(sun's) surface.these waves got higher and higher and make a mountain, which got separated and plants or our solar system came into existence.this shows that stars exist before the big bang. we have a common theory about black holes that when a star or stars collaps completely, a black hole came into existence(if i am not mistaken).what do you think about that?.

Hi Sumbul  Arshi
I think you should read a bit about what the words that you are using actually mean in Science.
"The Big Bang" was not just at the formation of the Earth, it was thought to account for the beginning of the whole Universe.

The idea that a passing star drew a stream of matter from the Sun which then coalesced into the Solar system was a popular theory in the early part of the century but of course it has long been disproved.
