I discovered a wild theory about humankinds past.

Humans evolved to bipedalism because the food was on trees. Just simple as that.

Nah. Many non-bipedal animals are able to eat food from trees.
Evolution did it so that we could look better in suits, dresses and movies.

Then why did they ever leave the trees?

To pick up the fruit that had dropped from the trees?

There are at least twelve distinct hypotheses as to how and why bipedalism evolved in humans, and also some debate as to when. Bipedalism evolved well before the large human brain or the development of stone tools.^[25] Bipedal specializations are found in Australopithecus fossils from 4.2-3.9 million years ago.^[26] Recent evidence regarding modern human sexual dimorphism (physical differences between men and women) in the lumbar spine has been seen in pre-modern primates such as Australopithecus africanus. This dimorphism has been seen as an evolutionary adaptation of females to bear lumbar load better during pregnancy, an adaptation that non-bipedal primates would not need to make.^[27][28] The different hypotheses are not necessarily mutually exclusive and a number of selective forces may have acted together to lead to human bipedalism. It is important to distinguish between adaptations for bipedalism and adaptations for running, which came later still.
Possible reasons for the evolution of human bipedalism include freeing the hands for tool use and carrying, sexual dimorphism in food gathering, changes in climate and habitat (from jungle to savanna) that favored a more elevated eye-position, and to reduce the amount of skin exposed to the tropical sun.

So they could pick the apple from the tree of knowledge and gain access to the plemora without the demiurge, who was unable to access the plemora himself?

I think the aquatic ape theory makes the most sense as it explains a number of things which are a mystery in our evolution. It explains why we are hairless, why babies instinctively hold their breath underwater (unlike all land mammals) and why we walk upright as drowning is a very good why of ensuring that those who do not stand upright do not pass on their genes.

So they could use weapons to ward off predators,or go out as Hunters ,not so long ago the Zulu nation used to send out teenage boys for a period of time,armed only with a spear,a knobkerrie (club) and a shield,if they survived and brought back a predators tail or ears they were regarded as true warriors,if they returned empty handed (no evidence of having killed a predator), they were still regarded as having passed the initiation into Adulthood, but were given other tasks,like guarding the village perimeter, or as herders or lookouts,and were classed as none fighting men.

Or it would if we were vaguely fish shaped like whales and dolphins. Mammals that are not fish shaped (even those who spend a ton of time in the water) tend to have hair.

That's just untrue. A common cost effective way of ridding a bunch of dogs or cats of fleas is dipping. Basically, you mix a batch of poisonous water and make like John the Baptist. I've seen it many times on both dogs and cats and never once saw one come out of the water coughing or dying from a lungful of poison.

If floods were frequent enough and of long enough duration for the difference to have any effect on reproductive viability, the world would be crawling with bipedal deer, dogs, and horses. It makes no sense that such an evolutionary pressure would affect only us.
