Wait....
All this happened in the last 6,000 years?
How does this take into account the dectable differences in materials with a terrestrial origin and an extraterrestrial origin? That is, material that has it origins in outer space has a noticeably different composition than material that originates on earth.
Meteors and comets crashing into earth creates sedimentary rock?

This is just another example of YECs completely making stuff up with NO supporting evidence.
Note: It seems to me you may not be a youth earther in the strictest sense but may be an old earth, recent creation of life (gap theory) proponent. But if you accept an ancient earth, why bother making stuff up about how oil and coal came to be formed?

Whoever calls me ignorant shares my own opinion. Sorrowfully and tacitly I recognize my ignorance, when I consider how much I lack of what my mind in its craving for knowledge is sighing for... I console myself with the consideration that this belongs to our common nature. - Francesco Petrarca
"Nothing is easier than to persuade people who want to be persuaded and already believe." - another Petrarca gem.
Ignorance is a most formidable opponent rivaled only by arrogance; but when the two join forces, one is all but invincible.
