Doubt it, there are 100 billion stars in our galaxy, and about every 5 of them have planets orbiting them. And there are many galaxies, numbers become meaningless, and there are many that are thousands of times larger than the Milky Way. But it is big, the distances are enormous, but I think it is unlikely that only a tiny fraction of one of them has intelligent life on it, although I question whether humans are as intelligent as we think, then we had not polluted our thin atmosphere with carbon that warms the climate to a limit that will soon be irreversible, so we wipe out the basis of life on the planet, for what, that a few people should have enormous incomes. Meaningless. So I sincerely hope that we are not alone, because then the universe will be sterile for intelligent beings in a short time.
