So why do you trust the science that determined those chemical composition but not astronomical science? They've use chemical properties to determine most of what they know about astronomy.

"These things have, to my knowledge, never been observed or proven."

Perhaps the most convincing line of evidence supporting this theory are observations of the same process currently happening elsewhere in our Galaxy. It would be strange if our Solar System formed in a different way to every other system in the Galaxy, since physics is supposed to work the same way everywhere. We see stars forming in the depths of giant clouds of gas and dust, and we even see young stars with disks of debris around them, which look just like the debris disk we think the planets formed from.
