Typically ignorant response, blue bunny.
First, to whom are you referring to with "they're"?
Because I didn't say anything about being sure that anybody was wrong about anything.
You, with your limited comprehension skills, read into what I wrote, what you want to believe.
I'll help you out. I used the word "may", so you'll probably want to look that up.
Also, I was talking about science in general, ya know, the scientific method, so you'll probably want to look up that as well.
Sigh... I don't have the patience to explain what's obvious to you on a regular basis. Plus, it's tiresome.
