The Bible explains............God created everything.............. If you are an Atheist or worshipper of false god, then how can you be existed in this planet?
I will let the "false god" slight go, but I really shouldn't.
Anyway, there are many creation stories. And there are even non-creation stories. Yours is just one among many.
I like the one from the philosophy of Jainism. I probably won't ever support Jain because the swastika is so prominent in their symbols, and despite it's pre-Nazi existence, I really don't want people thinking I am a Nazi.
Anyway, Jainism does not support belief in a creator deity. According to Jain doctrine, the universe and its constituents—soul, matter, space, time, and principles of motion—have always existed. All the constituents and actions are governed by universal natural laws. It is not possible to create matter out of nothing and hence the sum total of matter in the universe remains the same (similar to law of conservation of mass). Jain text claims that the universe consists of Jiva (life force or souls) and Ajiva (lifeless objects). Similarly, the soul of each living being is unique and uncreated and has existed since beginningless time.
I could go on and on within your thread (and I may do so later) about the creation myths that are almost as strange, sometimes stranger than the myth from the Bible. But they all have this in common- they either say that something came from nothing or that something always existed without being created- all of them.
Many have outgrown Santa Claus and the tooth fairy and many have outgrown creation myth.
