Sometimes I wonder if all those “mythological” hybrid creatures weren't so mythological after all.
If one believes there was a world-wide flood, of which there is geological evidence, Biblical reference, and common stories from multiple cultures, then we know very little about civilization before that time.
Here's another thing I wonder about.
The most ancient Hebrew pictograph for the alphabetical letter “nun” looks like this.
It's supposed to be a “seed” and means “continue, heir, or son”. To me it's obvious what that is, a classic sperm cell. But this raises a question. How would anybody back then be able to see that without the aid of a microscope?
Are we just progressing back to a past that nobody remembers anymore? If so, it didn't turn out well the first time. Couple this thought with modern human nature and we're on the fast train to unleashing nightmares that would never exist if genetically left alone.
