Do Aliens actually exist ?

Observable light. Millions of years through to Billions of years. It may be that intelligent life can only evolve later on in the life of a star
Yeah that’s a key point, when observing these galaxies, we are looking very far into the past but I read that they were expecting to see at least one, as there would be enough time since the beginning of time, but they didn’t and were shocked.

Sorry, expecting to see at least one what? And who didn't and who was shocked?
 
The trouble I've always had is that anyone that I've ever known who's claimed to have seen a UFO has immediately followed it up by saying "I've seen a ghost as well you know" which straight away dilutes the chances of me believing them.

Ghosts do exist mate, it's just that you can't see them as you aren't tuned into their frequency.

I read that scientists expected to see galaxies with the light slightly dimmed, from other civilisations harnessing the energy from stars. This would be a civilisation that had colonised the entire galaxy at that point.

They expected to see at least one galaxy’s light affected and were surprised there wasn’t any evidence of light across the whole galaxy being interfered with.
 
I forgot the Femi Paradox possibility of massive Gama Ray X-Ray bursts sterilising a galaxy which decline as the age of a galaxy increases.
So we may actually be the first intelligent life - much like the Vorlons and Shadows from the Babylon 5 Sci-Fi universe
