Space is huge and there are more stars than you can count

[Lilith7]

I was watching a video recently about the lack of aliens...like, we should see them right ?  But are we early or late into space ?  They think we are early...other planets may have beings getting into space right now, but we won't see them for millions of light years.  The place is just too damn big !

You are theorising based on your own (a human's) abilities and experience.

Firstly the species on Earth are carbon based lifeforms. This may well not be the case for those from other galaxies, or even planets, where 'life' may not necessitate having a physical manifestation.

Secondly we 'see' in a relatively narrow segment of the electromagnetic spectrum so an alien may well be in our midst without being detectable using our sight if their realm is present outside of our visible light spectrum. That's if they even exist in a physical form (of a scale) that we recognise.

Lastly we don't have active communication with many lifeforms in our own environment (invertebrates, bacteria, fungi, etc) so why would we readily have the ability, or inclination, to do so with those from outside our current sphere of awareness?

That's an interesting line of thought; we could actually be in contact with aliens without realising that they are aliens.

Fog, for example could be an alien life form - which we've somehow simply mist.

Sorry, sorry - completely unable to resist!
