Science fail. Critical thinking fail. Circular logic, epic fail. What a fine argument against home-schooling.
You idiot. Firstly, why do we even have these vast fields of stars, extrasolar planets, asteroids, the Oort cloud, and basically anything beyond the orbit of the little dirt speck your 'god' ostensibly created.
Asteroids? A planet or other body that didn't make it. Sol's belt is a loose-strewn collection of leftovers from its younger eons.
Exoplanets/in-system worlds? Primordial matter that simply happened to condense differently than Earth, over a few billion years.
The Moon? Earth ate a Mars sized entity during its formation. Violently. Unless you're one of those idiots that believes we didn't land on the moon (Neil Armstrong would like to chat with you in that case. Probably with a solid slap), we have samples of the lunar surface that reasonably confirm the theory.
There are logical answers to your questions. It's a pity you're too lazy to actually do the research, instead flapping your arms about, exclaiming Goddiddit.
Secondly, perhaps it hasn't quite occurred to you that the same argument you use to justify that Goddiddit applies here, also begs the question Whatdiddit, to make your god in the first place? Oh, wait. 'He' is magically exempt from needing an origin.
And people look at me funny when I wonder why the religious aren't institutionalized. If you're really genuinely this ignorant, any 'education' you may attempt to give your children could be well and truly considered intellectual child abuse.
