A trillion attempts to get it right, and I thought I was shite at my job. It's odd that the bible didn't really have too much to say about the other 4,500,000,000 years of history.Many of them before the Milky Way so maybe he kept creating them until he got one right. The ones created after show the Earth isn't perfect.
Maybe god got bored, created humans and now we're killing everything and screwing it all up, he's a sadistic bastard this god of ours.
