A thought, discuss please.

Assuming that you could plot every action of every creature, plant, pebble, and ocean stream, could you in fact know the future?

I don't believe it's possible to predict the future with 100% certainty.

Say an anvil is falling, and you see it's going to land on someone standing on the sidewalk.  Of course, you could say that the anvil will hit him, but what if he moves?

I could go either way on this issue really, but that was the only way I could actually back up my claim.
