I have been thinking about extraterrestrial life recently, and was wondering about what y’all think of it all. Do aliens exist, or are they just another piece of nonsense on this lonely planet? I personally think they should be, in some form, real. This is why I think that: (a) This universe is HUG…

Organisms that move quickly evolve a concentration of sensory organs at the front end because that’s the part of its body that first encounters dangers, foods, etc. With all those sense organs at the front end, nerves tend to be concentrated there, too – a brain. Also, the organism becomes bilater…

I believe aliens do exist, but not as little green men. Out of all the impossible, terrifying, weird and wonderful creatures an extraterrestrial could look like, it converges on a human-like form?

Astrobiology is a super interesting field, I’m glad more people are starting to ponder about it! Part of me hopes that we are indeed the only life forms in the universe. This would mean that humanity exists in a giant sandbox, free to explore, without threat of meeting hostile aliens! But, humans a…

There are too many possibilities to not be the only planet that has life. There are for sure planets with the same distance from their parent star which means those planets will have similar climates to us which enables life to exist on the planets. However, there may be life existence on planets th…

I’ve not been positive that humans are not the aliens here.

In my personal opinion they don’t exist. The biggest proof for me is that despite the fact that we have organisms living in pretty extreme conditions we have not found a single shred of evidence of extraterrestrial life in any of the other planet in our solar system and seeing how for us to be alive…

It would be interesting to see if there was a viable alternative to proteins and DNA/RNA to build that life on. I could imagine that alien life forms might be based on a similar biochemistry to ours - different in the details, but based on the same types of molecules, playing similar roles to what …

Considering the tremendous genetic and biochemical similarity of humans to other organisms on this planet, the hypothesis that humans did not evolve here (are alien to earth) cannot be supported.
