What to say when somebody asks about the big bang

[Czechlervitz30]

This is my first actual post that is not a greeting.

I'd like to start out by saying that I am only sixteen years old; I know that it may seem irrelevant but I figured I'd just say so.

I have many atheist friends but some are religious. And being in the nature of friends, they will ask me questions about atheism. I'd also just like to know this for myself, because I am not entirely sure.

What do I say when somebody asks me about the Big Bang theory?

Anything from what happened before it, how did it start, etc.

I am aware that there is never a clear answer for this. I just would like to know if any of you have any quick and easy explanations for it.

Even if I, when asked this, cannot explain what it is, I can just turn it back on them. Ask them about the origin of God.

I want to thank you in advance for any future responses to this.

Have a fantastic Sunday. :p

Tell them that the universe is expanding which means it was once at a singular point and exploded. I found an article that says that the scientists actually theorized back in the 1920s it was more of a big bounce from a previous universe that collapsed in on itself.
