Hmmmm?

I wonder why when God created the earth and Adam and Eve, why he never mentioned to anyone that  the earth was only one of billions of stars. Curious. And out of all these billions of stars (and who knows how many planets) why did he choose earth for his "only begotten son", especially since it was one of his much smaller creations? It's certainly is a mystery. And since science has proven that Earth itself is billions of years old, why did he wait so long before causing a ruckus just a few thousand years ago? What was he waiting for? There's no question that the bible is absolutely gospel truth,  but still when one considers the vast and endless universe, it does make you wonder.
