"People assume that time is a strict progression of cause to effect, but *actually* from a non-linear, non-subjective viewpoint - it's more like a big ball of wibbly wobbly... time-y wimey... stuff"
Time is a location, with coordinates stretching infinitely in both directions. Asking why we exist now instead of then is like asking why we exist here instead of over there. LoL. For that matter, how do we know that we DON'T exist then? Our "0" or now is a completely arbitrary point.
I don't know about other people, but I like this topic.
