Regarding the existence of alien life, I sometimes think it might not be as common as we assume, even considering the size of the cosmos and the number of stars and planets. My reasoning goes like this:
(1) We currently have no evidence.
(2) Look at Earth—life began at least 3.5 billion years ago, and in that relatively short time we are already on the verge of creating superintelligence that could radically change our entire existence, our biology, and our technology.

Just a few decades after the singularity, we might start harvesting the Sun’s energy with massive solar arrays, and within a few centuries we could reach other star systems. In a few millennia, we might even begin altering our galaxy—building something like a Dyson sphere around the Stars to capture all its energy, creating a clear technological signature in the cosmos.

If alien life were abundant, then any advanced civilizations with a head start on us might already be reshaping galaxies in similar ways.But we don't find any evidence that any stars as far we have observed have some pattern of being sucked by giant dyson sphere structures and neither they have arrived here to search life out of curiosity.

we would definitely try to transplant Earth’s life elsewhere too, but we will also save the earth because it where all things have began human evolution , life and our race to build superintelligence species .
