Creation theories from my 5 year old son

So Mummy, there was a really, really, really big bomb and then it exploded and do you know what popped out when it exploded? Earth. Earth popped out. But do you know who threw that bomb? Do you? God threw it. Yeah, that's right a god threw it. No. No, no, no, actually Mummy a god didn't throw it. Cheryl Cole threw it. Cheryl Cole started the earth. I'm only kidding about that last bit.
