Currently the age of the universe is pegged at about 13.5 billion years.I assume they are intelligent beings and would not travel hundreds of light years only to buzz the night sky and go home.
They may have technology more advanced than we do but they still have to deal with the same rules of chemistry and physics
Age of Sol and Earth about 5-4.5 billion years.
We humans are late comers and children in that time scale.
"They", some at least have been here a long time before we humans and have stayed.
"They" hold the lease and title to this System. We are the 'cattle' that come with the 'farm'.
