When you look at the night sky and see all those stars you are really just looking at all the failed attempts at life. If life happens in 1 in a billion stars then those stars are proof of all the other failed attempts at life.

Stars making attempts at something would imply that they have some kind of objective which isn't the case, but with other small random wording/semantic issues aside, I agree with most of what you said.

As Richard Dawkins said, I think that "Life results from the non-random survival of randomly varying replicators."

We are just as mechanical as viruses which aren't even said to be alive. Viruses are only sets of RNA or DNA that purely and mechanically replicate when provided the energy of something else. Just because we generate our own energy after stealing it from something else doesn't make us that special or different. This five minute video is pretty good and explains this in more detail.

People are a part of nature. Societies, cities, etc. are somewhat like jungles in that sense. In the end, anything goes, and does--from the top levels of society to the bottom. Some people are smart enough to perceive society and understand its inner workings enough to use it to their advantage, and others are not. We are more animalistic than basically any other creature on the planet if you really think about it, and intelligence just allows us to hide it even though it without a doubt there running 24/7 in raw form in all of us.

Societies, traditions, and culture experience evolution and survival of the fittest just like a person does. If one culture's way of being is subpar in some major way, it naturally gets wiped out while the others thrive and continue to produce variations that continuously experience similar tests.

People are easily influenced which is why they will identify themselves with any religion or cultural way of being at an early age even though they would feel the same way about almost any other kind if born in a different place--at least until later years when people can start to use logic to break through those barriers.

In the end, life is just a really strange, rare, but natural phenomenon in the universe with identities, for most people, being given to us instead of being built ourselves. Our consciousness is purely mechanical in nature as well (and I don't think we have free will). If you kick open an ant hill and see all of the ants moving around, and imagine the inside of a building where you could see everyone simultaneously moving around; or look at a city from the sky and then look at bacteria growing on a petri dish, you'll realize it's all the same shit with varying degrees of complexity.

I covered physical life, cultural life, evolution and identities and their role in things, etc. I think that pretty much covers it.
