We seem to underestimate the mental capacity of humans that lived hundreds or thousands of years ago. The fact is, we are no smarter than they were, we just have the advantage of thousands of years of history to learn from, but it seems some people have to learn everything for themselves. There is no evidence at all that the human brain has evolved at all during the last fifty thousand years! Do you know that some of the things that we attribute to modern times were actually invented back many, many years ago?
Let us take a metal that has been used and associated with modern man, say aluminum for instance. Archaeologists have found aluminum ornaments in a tomb of a Chinese soldier who died in the year 297. And what about gun powder? We picture the ancient people fighting with stone tools and wooden spears. No, I am not saying that they came up with guns in that year, but they did discover gunpowder. In a quirk of fate, they were trying to come up with an elixir of immortality when they discovered something that has caused enumerable deaths throughout history.
I just thought that you may get a kick out of some of this information. It is wet and cool out there today, so keep your powder dry and have a great day anyway, you hear?
