True, but aliens in general are insanely likely to exist. Humanoid aliens are quite stupid, I agree, but aliens that are intelligent or function in similar ways to us are likely.
Also that doesn’t support your argument that aliens don’t exist, it supports the argument that humanoid aliens don’t exist.
it is possible to confirm. locate process created by natural life and see whether they are abundant. Like oxygen. Planets with life will have higher levels of oxygen in their atmosphere then they normally would. this can also be done with other natural process that are produced quickly by animals. I saw a youtube video on it once. They checked the information with Earth as a satellite was leaving.
I honestly am failing to understand the people who say alien life does not exist
like, intelligent life might not exist but… there’s all sorts of types of life
ever heard of extremeophiles? life always finds a way to thrive even in the harshest conditions, and on a hypothetical planet with running water and a very basic atmosphere, anything can happen.
thinking that only earth harbors life is very biased and I strongly do not think our planet has any special treatment.
