Chances are that aliens have a head start on us by billions of years.

Population III stars were formed 13 to 12.5 billion years ago, and probably none remain.

Population II stars are low metallicity and probably do not have Earth-like planets. They tend to be near the center of galaxies.

Population I stars like our Sun, that can have planets, are high in metals, mostly are in the spiral arms of galaxies, have a lifespan of about 10 billion years and were formed roughly 1 billion to 1 million years ago - except that our Sun is 4.5 billion years old, so it is among the earliest of the Population I stars.

That will probably sound like bad news to extraterrestrial enthusiasts, who hope Earth is more recent so that more ancient, more advanced civilizations could exist, which might give them the capability, time, some very good reason, and somehow the resources to get here.

But it would seem that the opposite is true, and that our species - practically just out of the Stone Age, might be among the oldest and most advanced in the Universe.

The little green men might not even be amoeba yet. Assuming there even are other forms of life. Sorry guys.

Maybe we should try not to blow ourselves up, because there are no advanced creatures out there to save us...except God. And He will only save us in Eternity, not on Earth.

I might add that when the military spends money on UFOs, its probably not what they are really spending it on. Their experts already know about this. So when the media tries to scare you about ET being evil, don't buy it.
