There are some small grammar-punctuation things I'd have pointed out. I do think it should be "our children," or "the toddlers," as "our toddlers" feels to me to break the flow, and I wouldn't go for toddlers anyway.

It is interesting though, that you consider this the greatest sin, and greatest tragedy, not being cast from the Garden, for instance. And the sin wasn't humanity's, but the angels', or demi-humans', back then, which led to the flood. At least to a largest degree.

Besides, the covenant God struck with man after the flood, he said that the rainbow is his mark to remind us he will not repeat it, so you can't blame everyone else for the colourful palette, when God tied the rainbow to the flood as well.
