That does not make any sense.

Which part are you confused about?

Yeah, I feel like Omniscience is knowing the past present future and beyond, knowledge about infinity that continues for eternity, basically having an all-seeing eye because to have complete the complete history of it down to the molecules. This character would have a predetermined fate if he doesm't have a paradox defense

And the effect of omniscience to a mortal mind is just sht, I think the closest thing i've read that have the mc experience something close to omniscience is him being chucked into the source wall of DC, he became insane the instant he made contact to it due to how much information he's getting and him forgetting it the next moment because of how overwhelming it is being bombarded by information.

It makes total sense actually if you have omnipotence then you can give yourself omniscience and omnipresence if not then you aren't omnipotent and the same goes for the other two if you have omniscience then you know how to get omnipotent or you know how to do everything because you know everything you can bypass the laws and concepts that bind your physical limitations because you know how if you don't then you're not omniscient

forgot to add this if you know everything why would you need omnipresence???

You confuse knowing with doing.

you would how to do it even if it is impossible by human logic because you know how to everything in an 'infinite' ways.

Lets brake it down, you know how a baby is made so create one out of thin air.

Well I don't would not know how to do that but an omniscient person with infinite an knowledge would because they know how to do everything no matter how illogical it is

They would know how to create a baby in a infinite way (not just our understanding) because they omniscient.

so know only equals doing then? can a all knowing person kill an omnipotent being

Immovable object vs unstoppable force

Knowing how to do everything isn't the same as being capable of doing everything.

he's saying that for you to know everything means you would be able to do everything because knowing everything would allow you to know how to accomplish or proceed to doing it, like making a baby out of nothing, he would know how to do so for he knows everything.

Bro, you can't make something out of nothing because there isn't a way to do something out of nothing unless you're omnipotent or have a specific power for that and even so, it would still be because of the power, so no, knowing everything isn't equal to being able to do impossible feats, he just knows everything that there is to know, and not something like pull baseless knowledge out of his ass and make it into something feasible. At least this is my thought.

I'm saying that for you to know everything, you should be able to get to the point of being able to do everything, like if you knew how to build something all it would take is getting the things you need to build it, so if you know everything you should know a way to make things out of nothing as long if you follow the "instructions" to be able to do so.

let me break it to you all, true omniscience in marvel can let a human achieve the other omni's as he would know everything including how the celestials/Franklin Richards/Galactus/living tribunal how their powers were gained or how they were created and thus find a simple way to just draw the energy from where they got it by using runes for example ofc, he could use many other ways I don't know and gain power like theirs easily and thus keep getting stronger by using other knowledge he knows for becoming like the OAA as it is said the OAA created himself so he has to know the how to do it himself.
