How can't Christians not see how contrived this all is?

Tell me: Where did the first atom ever come from, that split into two, then four, then eight,... into all the stars, moons, planets,... into earth and all that is on it, from water to rocks, fish to worms, birds to seeds, flowers to fruits, foxes to snakes, bears to elephants,.... into us with ability to Love? Where did that first atom come from?
