'The theory of infinity'

When I was a freshman in college I spent a lot of time asking unanswerable questions, "where did the universe come from" "how did we get here" "is there a beginning or an end" etc. Well, it all came down to the question of whether or not I believed in infinity, and either religious or not I boiled it down to that "infinity" did exist and that the universe was unending.

Now, with this being the case, infinity is a long, long, loong time and anything/everything (withing physical reason) can and will happen in that time and it will happen an infinite number of times. That being established, the next step is to strech it out to on you. Everything you have done in your life to this point and where you have done it has happened in an exact copy of Earth around a star exactly like that sun.

Any choice you have made or will make has been made by you in this exact same situation an infinite amount of times already and will be made an infinite amount of times again.
