I find it difficult to satisfy the Drake equation such that there is intelligent life in the Galaxy but also that their isn’t abundant intelligent life in the Galaxy. Essentially if one race achieved FLT then their should be a universe teaming with races that have FLT.
Or life is truly rare. There is a very limited range of variables which would satisfy a universe in which we haven’t detected other life and that life is close enough to visit us. The range of variables in which there isn’t intelligent life visiting us is far larger.
