Do you think that aliens exists?

I believe they do and i think all the evidence that has been shown recently is evidence of that.

maybe some small bugs on a planet thousands of years away from us

It's like asking does it rain in the ocean, of course it does and of course there are aliens... it's pretty impossible that we're the special species in the entire, seemingly endless universe of cosmos, just alone in the Milky Way in Sol, on Earth, no other life forms out in the galaxy or in Andromeda... it has to be impossible, right? Makes you think a bit lol

Like tscollector says, we're aliens to some other species out there, a species that is going about their day right now, a species that doesn't believe WE are real.

If there are we may never see them. Unless we discover FTL travel we may never even leave our own solar system.

aliens exist but they could be cells or even something the human mind cannot comprehend.

Absolutely! There so many evidence by vid on youtube!

Ofcourse! But maybe not right now...
I believe we are too early to see anything like that

maybe yes. universe not small and also human not only

Yeah, they just haven't come here yet though.
