LOL!!!
These threads provoke me to pondering and a desire to sort out all the remarkable discoveries that have occurred in such a short period of history.
I wonder how we would begin the fundamentals of metallurgy, horticulture, domesticating animals for fur and meat, creating tools and vessels or modes of transportation.
Our ancestors were so inquisitive and resourceful- even though I suspect many discoveries were totally accidental.
Innovation was probably accidental in some cases, but I think that we have always had our geniuses and scientists, thank God.
Half of our discoveries, at least prior to the past 4000 years, came about because men love to throw s*#t in the fire.
