Your list of "qualifications", and how often it grows, is consistently astounding.
Your resume must be rather daunting!

Anybody who says: "Scientific theory is NOT the hightest form of knowledge. It is THEORY." has just DEFINITIVELY PROVEN that they are fairly unfamiliar with science. You have no concept of what "theory" means in science, and the importance that is laid upon that word...
You reference it with the same mistakes that a lay-person would...

The truth of the matter is that there is no real dispute on the age of the earth (to the degree you are disputing it) in SCIENTIFIC arenas. Any "dispute" on the matter typically comes from RELIGIOUS perspectives, based on RELIGIOUS tomes with NO science to back them up.
Your replies on this issue have typically come from the realm of throwing out questions without actually substantiating the VALIDITY of those questions...

And for the record, it's not the "challenging" or "disagreeing" which makes you come across as ignorant. It's the ignorant statements you make which comes across as ignorant.
Moreover, I don't think you are "challenging" anybody's view on this issue. You're tossing out lame speculation. Asking questions which reveal your own ignorance of the subject instead of demonstrating repute of the issue at hand.

To "challenge" a scientific conclusion, you would first need SCIENTIFIC EVIDENCE to base your challenge upon.
You have none. None whatsoever. You haven't even tried...
Plenty of "what if" questions demonstrating you aren't familiar with the topic in the first place... But no facts.
