According to meteors, there should be abundant life in the universe...or has been....
Seriously though
IF I were another species from space, I would not want to be involved with humans. We are violent, destructive, barbaric to the extreme especially in the name of religion and technologically advanced enough to do major damage militarily and biologically to any other species.
Were I an alien, I would remain hidden, watch, study and isolate humanity from any inter galactic community

Life is rare in that only a small percentage of any particular galaxy is suitable for even bacterial life to form, but goven the vast number of planets in one galaxy it need not be VERY rare. However, complex life would ne far more rate and HIGH intelligence even less common.
BUT....
If we are talking about the universe, with its virtually infinite number of galaxies then even intelligent life must be prolific.

Except that the Earth formed 8-9 billion years after the big bang and by most accounts, galaxies formed less than half a billion years after the Big Bang. That suggests that the conditions for life developed 1-2 billion years after the Big Bang. Once a civilization develops, if it survives long enough to develop faster-than-light travel, they could seed any number of planets, perhaps all that can support it.
That is only one reason why the Drake Equation is BS.

IMO No it's not---just look at those Tube Worms living under tremendous pressure in deep ocean trenches at the Very Hot mouths of underwater volcanoes.
Now, if ya wanna talk about Intelligence, i am right there with ya!

Any intelligent alien species would isolate the earth like in a zoo where the semi intelligent wild animals are cared for but cannot harm the civilised alien worlds.
@vocaloldfart Time. Earth is 4.5 billion years old. Humans have only been here go ½ million years. "They" probably don't exist at all and certainly not at the same time that we exist. If they can observe us from 1 million light years away, we don't exist yet.
@barjoe you have me confused as to what you are trying to say. I cannot understand why aliens have to be 1 million light years way from us, nor can I assume they have the same technology as us at present.
According to archaeology, the Australia aboriginals have showed signs that they were here over 125.00 years ago. their dreamtime stories accurately describe events that happened 250 000 years ago.
All over the world there are stories of mans exploits in religious and history books that are now being questioned and discovered to be a lot older that previously thought and taught. New technological advances are breaking down the misconceptions of the past.
You seem to have your aliens neatly in one box. I however prefer to keep an open mind and make no assumptions at all, just extrapolate from pure logical thinking
@vocaloldfart Do you have any evidence of extraterrestrial visitation in earth? No? I didn't think so.
