Well lets assume for a few minutes that you know everything you can do anything and you are able of possible and impossible and literally you have all the knowledge there is, what will you do?
Wouldn't you literally start the creation so vast and huge as the universe of ours from nothingness?
Funnily enough given human beings so small and weak unable even to go to the nearest star while there are billions and gazillions of stars and considering our own solar system with hundreds of large planets, moons and asteroids there are even hundred times more of them than all the stars yet we have the audacity to question such a mighty force created all things or even denying (His) existent.
And you can now stop thinking that you know all and capable of all because you can't possibly, free will is the same thing as we can ask these questions but we can't really change things in large scales since every prophet showed up told people very simple things like hey dudes and gals if you do such things and avoid some other things you'll be all right.
I don't know what is so complicated for people to get it? you know you are weak and can't change everything, you know that you don't know much and there are for real forces at work, then stick to the things you were told to( I mean really research and spend time to see what you have been told to do) you'll end up just fine.
Now go around and ask what is the origin of life, you wont get the answers you are hoping since you haven't understand the more simple things yet.
