Actually, it is science. People who speak with 100% certainty are the ones that raise flags.

You called it!! Science no longer requires evidential rigor to the conclusion.

"Yea, that's science . . ."

Yes it is. Making hypothesis based on evidence and testing them. Not assuming certainty. That's how it works.

No real scientist claims to have all the answers, or puts more weight on his hypotheses than they deserve.
Words like "may" and "suggest" tell us we are looking at interesting hypotheses, not confirmed theories or observed facts.

Taken with the appropriate understandings, I think it's all fine.
