I won't actually create reality until all my omnipotence is returned to me. I was never willing to let my own free will be used for any duration longer than I myself had decided to delegate it.

The illusions of infinite time and space are convenient distractions.

Killing "wrong" of own specie may be it.

Most likely the step from prokaryote to eukaryote.

What are the chances of a prokaryote going inside another prokaryote. And the "host cell" feeds it the right proteines and the "subject cell" returns the chemical ATP which is exactly what's needed for high energy activities.

This development is only possible by a high oxygen atmosphere and is the only reason multi-cellular life is possible at all as non-oxygen reactions aren't powerful enough to power complex creatures like us.

The chances of it happening once is lower than the amount of atoms in the universe. Yet it happened on Earth. This sadly also means that we are most likely alone. Because the chance of it happening not once but twice is an incomprehensibly small number and there just aren't enough planets in the universe for it to become so lucky.

Hell that it even happened once in the universe against the odds is a miracle in itself. Prokaryote life is most likely fairly common though and we'll probably find some even in our own solar system.

Parasitism. As civilization grows more complex, there's less incentive to support it compared to supporting some subset. The large society is eaten up and dismantled by smaller ones, who then fight until there's a clear winner, who is also eaten from inside out.
The size and complexity required to make the leap to spacefaring civilization is too far past the point where social parasitism begins to win out. Only inertia can carry a civilization there, and eventually all that goes up must come down.

AI. It becomes sentient, it proceeds to exterminate life, then proceeds to realize that the Universe does have a goal and that goal is the equal dispersion of energy (i.e highest point of entropy), so it then proceeds to collapse a nearby start into a black hole, which is a structure that perpetually moves itself throughout the universe and swallows low-entropy matter to spit it out as useless high-entropy radiation.
Every single black hole minus possibly a tiny fraction are actually artificial black holes made by a collapsed civilization's psychopathic AI that has discovered the intended purpose for the universe and the energy inside.

>>10562686
probably when we can artificial create change. That is the end of evolution.

If by great filter you mean "step on the way to a starfaring technological civilization with very low probability of occurring on any given planet", there's probably dozens or even hundreds.

The great filter is when civilizations realize they don't really need all that energy and go back to fapping at virtual girls.

aerobic respiration + multi-cellular life.

finally, someone who gets how rare that was.

The only other life we will ever find is bacterial.

I'm a geologist. From the geological record we can see that
>>10562734
is 100% correct. Life took 3 billion years, doing nothing to create eukaryotes.

The great filter is us jerking off about not detecting aliens that emit radio at unprecedented power.
It's very easy, though. Distance will just make them undetectable because they too weak.
Also it looks like laser is the future of space comms. not ideal for detecting them.

>>10562686
The great filter are the jannies

Yeah we learned about this in my Biology class, and I don't think enough emphasis was placed on how fucking ridiculous this was. A bacteria entered an archea and instead if killing both, everyone was just chill with it. Like seriously what the fuck even is that.

Altruism.

Anime Waifus.

They are so strong they beat the non exclusivity principle.

The filter imo is the ability to transcend the material. As long as you consider yourself to be a body and not an idea, you cannot travle in space as it takes so much time. But if you dont think of yourself as of a mortal shell commiting a tiny part of a giant endeavor, but as of an idea carrier who cannot die, then the trip goes swiftly.
Thus I really hope humanity goes extinct and gives birth to someone less materialistic.

As for faraway aylmaos, dudes... We dont even know our system yet. There are like a dozen of places where our system can have life. What about cloud spores of Venus? Or underground gnome kingdomes of Mars. Have you heard of satellites? We might have a liquid carbohydrate life on Enceladus and fish swimming under the ice of Europe. You dont have to be on a planet to be alive

Theory-saving by those who believe a priori that the Universe must be thick with aliums.

Distance and the laws of physics. Magic doesnt exist and interstellar travel takes centuries while a single average sized drifting rock nullifies the entire effort by destroying the spacecraft on impact.

Just saying if you think something has a chance of 0.0000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000001, and then it actually happens, then your logic is wrong.
Such a thing can never happen.
If something happened once, then it has happened more than once.
The universe is so big that this certain.
The universe is teeming with intelligent life. The fact that we exist is proof enough mathematically.
If your idea of biology doesn't agree with the math, then biology is wrong. It's not the other way around.

evolution, selection pressure. if it happened it almost certainly didn't happen all at once, and there was a SIGNIFICANT fitness advantage for those that could start doing the things that led to a eukaryotic organism

Seems to me like you, like many others before, are greatly overestimating the drake equation and fermi paradox. check out this paper that restructures the dataset: https://arxiv.org/abs/1806.02404

>>10564472
if this really is the case, it's kind of fascinating to contemplate
