Are we not advanced enough to perceive alien life?

Do you think the reason we can't find life on the moon, the sun, the 70 sextillion stars, and the decillions of moons and planets that revolve around them is because we are not advanced enough to be able to perceive alien life, just like bacteria is not advanced enough to percieve human life. Maybe all alien life is so advanced that us primitive humans who evolved from monkey's and have only been advancing for 100 years can't comprehend civilizations of the moon and Mars, and Venus that are billions of years old and more advanced than us. Maybe they project their world as lifeless on to our eyes so that we won't invade their planet. Maybe they are holographic images. Bacteria can't percieve human life, but human life exists. Maybe humans just can't perceive alein life even though it exists throughout the universe. Any comments or suggestions?

I think that far more likely, the universe is such a unbelievably HUGE place, and with viable investigation into life traces just beginning, it would be utterly astounding if we detect anything this soon.
Although we have tried detecting signals for years with no luck, we are just beginning to use direct methods.
(And as an aside, the statement '... primitive humans who evolved from monkey's (sic)' is a common misunderstanding that NO evolutionist supports. Apes and humans evolved from a more ancient common ancestor. The divergence was long before either man or ape developed.)

There are all kinds of possibilities...

Maybe space travel is a phase that advanced civilizations outgrow, choosing instead to focus on something more important, such as teaching their children to appreciate the beauty of the world they live in.

Maybe advanced civilizations are impossible in principle, because producing enough energy for interstellar travel would irreparably damage the environment on a planetary scale.

Maybe advanced civilizations can only be built by learning (and evolving) machines floating in outer space close to a star (to draw energy from it), as living beings on planets don't have enough lifespan to learn what needs to be learned to build an advanced civilization and don't have enough energy to power their spacecraft.

Maybe there is a Pan-Galactic Pact Against First Contact; all intelligent races agreed to leave the emerging intelligent life alone to evolve as it would (we set up wildlife sanctuaries, why can't we be in one as well?)

That's why good science fiction is so much fun; it makes you wonder about these things...

Does your brain ever stop lol. You have the most amazing questions. Even if some are made up things lol.

Who are we to say bacteria can't perceive human life. Maybe it does and we don't know it. I don't speak to bacteria personally so I don't know lol.

I think that up until now, we've defined 'life' too narrowly and we've lacked some of the technology to find life. Now that we are looking for microorganisms and the methane signature, I feel we have greatly increased our chances of finding whatever is out there.
