Ya but it's not really backed up by that much data. Carbon based lifeforms could have arisen as early as the first billion years.
Yes, the first billion years... which is extremely early in the lifespan of the habitable universe. If life first evolved 13 billion years ago, and life on Earth evolved 3.5 billion years ago, we would still be some of the first life to ever exist because there's still an estimated 100,000 billion years of life left. This is backed up by an exorbitant amount of data.
This isn't something that was ignored in the fermi paradox. There has been enough time.
This is one of the more popular solutions to the Fermi paradox. This isn't an opinion piece.
I feel like we need to get on the same page about this one. 8% sounds really low but its trillions upon trillions. If earth is the only one so far, life is rare to the point we cannot imagine.
That's 92% of the planets that haven't even been formed yet. Life didn't arise on Earth for over a billion years after it was formed. And that isn't a statistic to tell you that 8% isn't enough planets, it's to tell you that we are so early in the lifespan of life, that almost all of the planets that will ever be habitable haven't even formed yet, i.e. if life isn't astronomically rare, then our planet is one of the first planets ever to form life.
Source please. Our galaxy is not the same as every other galaxy. There were galaxies early on that could have sustained life as far as we know it.
Still enough time for other life to have developed.
Our planet is one of the first in the entire universe to have life on it (with respect to the lifespan of the habitable universe), we've had life on it for at least 3.5 billion years, and it's only been in the last 100 years or so that we've been advanced enough to be able to listen and transmit to the extremely small portion of the galaxy we're situated in.
We dont know why it hasn't
Who says it hasn't developed?
or why we cant find evidence.
Sure we know why. The biggest reason is probably because we aren't even searching. Not really searching, at least. We don't have the technology or the drive to. We've only looked at 4,000 exoplanets in all of human history, and that's out of the 1,000,000,000,000,000,000,000,000 planets in the observable universe. Even if we had the drive to search and put some proper funding into it, we are nowhere near the level of technology to do so. We can't even imagine how we could do it. As our signals travel out into space, they become more attenuated until they are no longer perceptible through the background noise of the universe. The signals we have today can only reach a handful of habitable planets.
