Why I think our brains are so powerful

[Coelho]

Of course everything is aware on some level. Plants are aware of lights, air, soil in their environment, pests. However that was not the original argument. The original argument was that plants have feelings. Which is a complex function of the brain.

Show me a study or research article stating that plants have feelings.

Well, man, in this case im sorry. I meant the plants are aware, not that they have feelings like humans do.

We can prove that animals have a sense of fear, anger etc etc.

Can we? I think we wont never ever know how an animal actually feels like. We only can see their "outside" reactions. When we see a dog moving its tail, we infer that its happy. But we cant actually know how the dog is feeling inside its dogs mind. We can only infer, only make assumptions based on their behavior compared with our behavior. But we can not assume that the animals are feeling the same things we humans feel, that the animal emotions "feels like" human emotions.

Plants do not have the higher level functions needed to make emotions possible.

Indeed... plants cannot have human-like or animal-like emotions. But if we assume they have awareness, who knows how it feels like to be a plant?

I feel that if people are going to make such far fetched claims they should back it with some sort of research and try to reference where they found the data to support their claims; otherwise it's all just fairy tales made from heresay.

Well... unfortunately i cant back up my "fairy tales" with any scientifical research, as todays science still is not developed enough to research such things.
But if you or anybody else has curiosity about from where i, a scientist (physicist) learned and had my mind made to believe such things, look at:

The Art of Dreaming

It can seems absurd initially. But if you take your time, think about it for long enough, and keep an open mind free from any preconceptions, everything will start to make sense.
