Mankind's lifespan is constantly decreasing with time, along with bodily strength and intelligence -- not increasing (as the evo THEORY camp would have you believe):
According to linguistic scholars, all modern languages devolved from more complex ancient languages. When God first revealed language, it was much, much more complex than any language in common modern use, because ancient mankind was much more intelligent than modern mankind is. Language was originally designed with intelligence by God, and it was given to mankind as a gift. The original language of mankind is called Sanskrit, and all of the other extant languages on the planet are derived from Sanskrit, either directly or indirectly -- this is a well-known linguistic fact.
The Sanskrit language was mankind's original language, and it takes a total of 12 years to learn and speak it fluently. Sanskrit is presently known as a "dead language" because although it was once spoken all over the earth, by all human beings, it is currently spoken fluently by fewer than 100 people on the planet. This is because Sanskrit is far too complex for the less intelligent modern mind to understand fully and speak fluently.
Sanskrit is the most striking linguistic example of modern man's intelligence having devolved to lesser than that of ancient man. Other linguistic evidences include the other "dead languages," such as Latin and Hebrew, which are, to a lesser degree than Sanskrit, also very complex languages that are very difficult for modern man to understand fully and speak fluently.
The Greek language has also devolved over time, becoming less complex and easier to understand as time has passed. On the Foreign Service Institute's Language Difficulty Ranking scale, Modern Greek is a category IV language (meaning it takes 1,100 hours to learn), whereas Ancient Greek is not quite a category V (it takes 2,200 hours to learn), but is certainly more difficult and complex than Modern Greek.
All of this linguistic evidence means that language has become less and less complex, over time, as mankind's intelligence level has decreased over time. This trend of diminishing intelligence, as evidenced by mankind's irrefutably diminishing linguistic aptitude, continues to this very day, with language skills gradually getting lesser and lesser with each new generation of humans.
Not only that, but ancient societies with superior intelligence also produced superior technology to that of modern man. For example, modern man is unable to build structures such as giant stone temples and pyramids, for lack of technological knowledge, but everyone knows that ancient cultures did indeed have that superior technological knowledge.
Therefore the silly claims of Darwin were clearly false: Mankind is demonstrably getting less intelligent and more short-lived as time passes, and modern man clearly has less knowledge, less intelligence, and inferior language skills as well as inferior technology compared to those of ancient mankind.
