Life as we don't know it ... on Earth?

So is this the earth shaking announcement NASA piqued the world for?

[Sto Zvirat]

I wouldn’t call it earth shaking, but its damned interesting and it changes the way we look at biology. Its been theorized that life like this could exist, and now its been found. Knowledge and learning are good things.

Yes, it is exciting. Yes, they deserve more funding.

I just have an issue with making assumptions to such an extent that other possibilities are dismissed until a new “discovery” forces the scientific community to rethink their methods. Why not begin with the premise that other possibilities may exist even if we haven’t observed them?

[MHGinTN]

Does it work off of DNA information coding? Then it ain’t new, just new to NASA.

"If science hasn’t observed it, then it cannot and doesn’t exist? So dismiss it as a possibility until it’s “discovered?”

The possibility is never "dismissed" (The Scientific method does not Allow for that), its just that since we haven't found one yet(essentially, discovered), there is little reason to expect it to exist, and hence the surprise. And its absolutely essential that when we something unlikely or rare, one check the science and be skeptical about it. Skepticism is Not to be confused with arrogance though one can see why that might be cause for confusion. The default position in science is one of skepticism, not belief. If the sun decides to not rise tomorrow, you hardly expect people to shrug and say "Huh, Interesting...". It is a necessarily unlikely event which should be cause for surprise. Besides, any perception of arrogance is necessarily about the people involved. "Scientists" aren't a stereotypical group of people with simple characterizations. There are arrogant ones and humble ones, (mostly) lefty ones and conservative ones(like me) but they can, in general, Not be typecast.
