yes! finally a profound topic to reply about! I i think it also depends on what you believe in, if there's a God or not. see if you do, then it's like

God says: ok, i know (whoever) is going to say (option a) not (option b).
Whoever: blah blah blah(option a)
God: hah! I was right!

Therefore it's predestination, but on the other hand he gives us free choice, but he knows what you're gonna do or say.... so whatever

of course if you don't believe in God, then both are still equal options, it just depends on which one you choose

so either way it still could be both redestination or free will, choice or action coming first.... the chicken or the egg.....any way, it all comes to choice, which proves that choice came first, which in turn depicts that it could be either! so there you have it,...... a circular definition!
