We are all alive in the same way

That's not really a given. Maybe arguable for mammals, but arthropods? What about sponges? Fungi? Trees?

Not OP. I think the brain is more a receiver of consciousness than a generator, and there are many types of receivers, beyond neural cells.

Trees will form a network with the cooperation of fungi, to exchange information and nutrients among each other. Plants will grow better when they are planted with companion plant, or cultivated in guilds (https://en.m.wikipedia.org/wiki/Guild_(ecology)
