How did round planets form from the explosion of the Big Bang?

Ok, start at the beginning, I know that the mathematical probability of god is very bad. I believe in god, that is my choice, people who believe in evolution chose to do so and I respect that. Anyway, here is my argument.According to the theory of evolution to the extent of my knowledge, the universe originated from an infinitely small, infinitely dense and infinitely hot piece of matter. I'll start here. First, where did this come from? I know a lot of evolutionists do not believe in eternity, but matter cannot be created or destroyed, so where did this come from? Next, why/how did this material spontaneously explode? How did round planets form? Normally when something explodes, it is not round. Rock is denser than the gases in our atmosphere, is it not? So, assuming we have an explosion with sufficient material and conditions to create round planets, wouldn't there be a gas "bubble" near the source of the explosion?Any questions, post here or message me. Thanks.Edited by Admin, : Remove off-topic content, change title.

Well, By the mathematical probability of God I mean that we have not experienced a god. By belief in a theory, I mean that as of yet I am not convinced. I believe in god, but I do have some doubts. What you believe, you choose to believe in. Gravity is observable (please, don't get riled about this one) where as basically what I have heard on here nobody knows about the big bang theory, this is. So the universe was created through a space-time "gap"? Never thought of it that way. If the conditions were correct, particular gravitation could theoretically happen.
You have some interesting points, thanks for sharing.

Er... No I'm not trying to "bash" evolution... I have been homeschooled all of my life and therefore only learned Evolution/Big bang theory/Abiogenesis to the extent of my own research. Now, I have been to a few classes on evolution, but these seemed to bundle it together.
