We already know that there are likely billions of planets which are likely to be similar to Earth in terms of temperature, size and being terrestrial.
The only question here is that even here on Earth, out of the tens of millions of species, only one is capable of creating advanced technology.
I am almost certain life exists elsewhere, but likely not intelligent.
- x1798DE 11y agoHow similar is similar? Mars and Venus are "similar to Earth" in nearly every way that we could detect if they were exoplanets, but neither is capable of sustaining Earthlike life. I think it's far from a solved question how likely life is, given we have exactly one example of it arising.
- acqq 11y agoMy position is: even the intelligent life doesn't have to reach what some assume can be reached (Dyson spheres and stuff). We can't be sure we'll reach it until we reach it. Don't forget, there's enough nuclear weapons to roll us back to the prehistoric levels of existence. Don't forget the climate, etc. Before we land on any planet around any other star or have some other kind of proof, don't assume others do trivially. And, even if the advancement is probable enough, be aware that the other civilizations don't have to have good intentions. Better avoiding signalling around.
