His thoughts were as deep as his roots. As such, he wanted something to do with them.
So, he grew humans on his branches, each with a fraction of his wisdom to converse with.
But one human was not wise, but showed the attribute of obnoxiousness. As such he did not contribute to the branch society, so he was discarded to the dangers of ground.
But, the child did not die. Infact, he relished in the freedom ground life gave him, and forged his own life until adulthood.. But although his life was good, he still had great rage to the tree who discarded him. So one night the man approached his branch siblings. He carefully woke them, and extending his arm, offered an apple which the tree people meet with wide eyes.
The people bite each other free of the branches that held them, and ate for the first time in there lives. As the boy carved the apple between his siblings, he taught them how to chew, swallow and digest. This activity delighted the humans, so they followed the boy, who showed them more fruits, more plants, even meat. It was then that humankind realized it was not meant to photosynthesize. They were ment to consume.
