'Are We Alone In the Universe? New Analysis Says Maybe'

http://www.space.com/12421-alien-life-rare-universe-extraterrestrials-seti.html

>Tl;Dr: Professors state that just because life arose quickly on earth, doesn't mean it does so on other planets as well. Because the Drake equation doesn't take this into account, it's flawed and the number of life-bearing planets may be lower than we think.

Discuss.

Good point about the Drake Equation though it is flawed. Just because a planet could support life as we know it will not necessarily mean there is life.

>>Life arose quickly on earth
Really ? It took nearly a billion years once the planet formed.

I seriously hope you guys aren't still doing that.

quickly compared to what? you need a second sample in order to compare something

for all we know life evolved 10x faster in some other universe, and we will never know until we find it

>"Although life began on this planet fairly soon after the Earth became habitable, this fact is consistent with … life being arbitrarily rare in the Universe"

Professorfag from U of Tokyo there

This whole debate is stupid anyway. We can't even define life or intelligence and we don't know how big the universe even is.

So life that can live under certain conditions appeared after those conditions were met? But how do we know a different kind of life couldn't have existed under "non-habitable" conditions? It's just circular logic.

how the fuck do they know life is rare? we don't even know what is out there in 99.99% of the universe

cool small sample size, brofessors

seriously?

sorry, but my inner weaboo is tingling

doesn't sound too wapanese to me... but these professors are full of shit anyhow, they say the Drake Equation can't possibly acommadate different scenarios, yet they lay out the scenarios where life can arise.

This.

We don't even know everything about our own oceans. Let alone anything outside of our solar system.
