I believe if life is common than there must of been at least one group of aliens that at least attempted to colonize it self everywhere in space?
Unless humans are a extreme anomaly and that most other aliens don’t really care about space exploration, and just focus on their home planet.
The great filter is the idea that there is something that filters out most if not all of life in the galaxy. It could be behind us, possibly the cellular with how unbelievably rare the mitochondria development was. Or the filter could be in front of us such as nuclear war keeping most life from never leaving their planet and leaving a galactic imprint.
I'm taking microbio this semester, the cell is absolutely insane. DNA synthesizes messenger RNA, which tells ribosomes to take amino acids and form them into these perfectly ordered chains where hydrogen and oxygen line up perfectly to form bonds which cause the peptide chains to fold back on themselves, forming complex proteins. It's so ridiculously complex, it almost seems like magic.
Yeah it’s insane, like why and how the do these ribosomes just do that and do it so reliably. it makes me look at deism as being possibly just because it doesn’t seem like something that can happen without a creator.

I don’t even know what that means so yeah lol.

tbf, you cant really argue what likelyhood life is with one example, we only have the top of the fraction. it could be one in ten, or one in 10 quadrillion.
I think a somewhat opposite approach is better, life seems extremely improbable, and we have a single example of life, so we ask why life seems so rare. No one without an example of life would be asking why life is so improbable so for anyone or anything asking this question there is a 100% chance they will have an example of life. You dont go around asking why smoopityboopity is so rare, cuz u dont even know what that is.

Eh, the evolutionary mechanism is simple though, even if the process is complex. Those mechanisms that aren't as reliable are out competed by those that are, leaving us with mostly reliable ribosome activity (environment non-withstanding). What would be interesting to see is what those more unreliable methods looked like.
Not that this rules out deism, it's just that self-replicating biological life has it's own rules here.
I'm still not ready to embrace creationism, the primordial seas had a couple of billion years for the right ingredients to combine. On a long enough timeline even highly improbable events become likely occurrences.
I love this stuff. I kind of like the protein world hypothesis, which posits that in primordial seas rich with organic matter some simple peptides form and, over the course of incomprehensible amounts of time, combine together such that they become self-replicating. Though AFAIK the RNA world hypothesis is more accepted.
