I think one day when we figure out the mystery of God we will find out that evolution and all of creation was all part of a chain reaction started by God.  This is my instant soup theory.  In the beginning there was God who is in spirit form.  God has no arms or legs etc. because he is not made of any physical element.  Then God created the first piece of matter.  Scientists call the tiny things, quarks.  These tiny things make up the nucleus of an atom.  We know that every physical thing in the universe is made from groups of atoms, called elements.  If you combine or split atoms you can make different elements.
    E=MC2.  Energy is equaled to mass times the speed of light squared.  If you combined every atom in the universe into a tiny tiny little speck it would have the total energy of the universe.  It would be the biggest atom bomb ever.  That's the big bang theory.  The test that proves it is that nuclear bombs work, plus deep space telescopes detect background radiation in equal amounts in every direction.  So everyone agrees that the big bang started the universe but what started the big bang?
    If you were and all powerful, omnipotent god would you go around creating the universe one tree at a time?  That would take a lot longer than seven days.  No, you would make a tree grow from a seed, and that tree would make several seeds and those seed would make more trees which would make more seed on and on.  So you created one seed that spawned billions of trees.
    Well if you are going to create a seed which spawns a forest why not just make the seed which spawns the whole universe?  OK what's the formula for that seed?  E=MC2  remember?  Energy is equal to Mass times the speed of light squared.  The speed of light squared is a constant which is used as a measuring devise.  The important part of the formula is that it is an equation and both sides of it always have to match.  Say your constant is 100.  The total of both sides of the equal sign must always equal 100.  You can split them in half which is 50/50 or you can go 60/40 or 75/25 or what ever equals 100 percent including 100/0.
    God, having no physical body was 100 percent energy (omnipotent, all powerful) and there was no matter in the universe yet.  Then God started creating the universe with the first quark because how do you make something from nothing?   With something very very small.
    So there it was, the first quark, then God poured all of his power into it and the equation went the other way very rapidly! BANG!!! The big bang.
    Now God's energy was everywhere.  That little quark had so much energy that it could not contain it.  That energy turned into mass in the form of more quarks which joined together with more and more quarks which formed atoms and molecules which eventually formed the stars and the planets and rock and every thing else.  NO wonder he needed a rest.
    From small things, big things come.  The seed of the universe spawned the whole universe.
    The bible says that iff you have the faith of a mustard seed you can move mountains.  The mustard seed is the smallest seed of any vegetation.  If you have the smallest amount of faith in God you can move mountains because God create a whole universe out of something even smaller.
    I have a model railroad which has some small buildings and some cars and some people and even animals.  Sometimes I wish I could shrink down to their size and hop on the train for a ride or live in the tiny plastic house.
    God looked at the world he created and wanted to be able to touch it and feel it and see what it was like to live in the place he created.  For God, who has no physical body, he couldn't just pop up and automatically be a man.  How do you turn nothing into something, by starting with the littlest, tiniest piece.  Cells are the biological equlivent to atoms.  The smallest human cell is the sperm cell.  It only takes one sperm to get a girl pregnant.  So how does God become a man?  The same way men do.
