>How does your entangled fatty tissue achieved consciousness?

It doesn't. Humans aren't conscious. Nor are any other organisms. They don't have souls either, but that goes without saying since it's just an archaic synonym. Mostly this occurs because humans have painted themselves into corners morally-speaking, and they need justification to eat bacon or grow their population. And apparently "because we can and we want to" isn't the correct solution.

We'll never be able to "answer the question" because it is an absurd question on its face. "Where do we find the magical brain ghosts making us special" presupposes there is something to be found, and a negative answer proves only that we haven't looked hard enough.

>after all plants exhibit communication and response mechanisms that are similar to those in animals - without brain.

Were that line of inquiry followed to its inevitable conclusion, there would be a mass vegan suicide to look forward to.

This is a tired point of discussion, brought up exclusively by contrarians trying to be edgy. No one earnestly believes that they don't have free will, because if they did, it would result in obvious deviance in behavior. Everyone treats each other as if they have choices, and in turn behaves like they have choices. If the assertion is that we don't have free will, but are forced to (due to our lack of free will) to behave and believe like we do, than there's no difference in experience to compared to having free will, and it ends up in the pile of pointless conversations like what if we're a brain in a jar, or in a simulation, or whatever.

Isn't consciousness phenomenon that's literally derived from human experience? How can you have any definition of consciousness that says humans do not possess it, it's contradictory.

You appear to have a rather idiosyncratic definition of consciousness.

You apparently don't understand veganism and the ethics behind it.
