NASA on extraterrestrial life

I heard that Chuck Norris's DNA is made of arsenic.

LMAO!!! Awesome!

Interloper,

"If the primordial bacteria hadn't been able to make such a shift, we wouldn't be here today, nor would those arsenic beasties in Mono Lake."

My understanding is that the beasties were living a fine and normal life in Mono Lake but then a few got shipped to a laboratory that changed their diet from phosphorus to arsenic. It wasn't a natural occuring process, well human activity is part of nature but you get my point.

Ah. I reckon I didn't read that part very carefully. Well, if we weren't here today, then those arsenic critters definitely wouldn't be here, either.
