I'm sorry I can't tell if you're being serious anymore...

If the fruit garden you're referencing is the Garden of Eden... Then kudos, you really trolled me.

Otherwise, the main arguments of human origin 200,000 years ago (I think actually more since they recently--a few months ago--discovered human fossils dating back to almost 300,000 years ago) are that we came from Africa or that we came from Asia.

In either scenario, there were no fruit gardens.

There were no gardens, period.

In fact, not only were there no fruit gardens, but there was also no concept of "responsibility." Responsibility is a human idea, too. So defining what our responsibilities are can only be defined by humans. But there is no single responsibility set forth by any intergalactic natural laws of the universe. The universe could care less.
