Many modern people have a very limited view of history. They can only see or think about five or ten years into the past. They see history as boring and they think of the ancients as ignorant and backward. This was actually not true. What the ancients lacked was the modern accumulation of facts. An ancient Israelite would have been very puzzled and culture-shocked to have been dumped into the modern world, but he or she could have eventually learned to drive a car or to cook on a stove or to use a cellphone.
The
ancients were just as intelligent as we are but the accumulation of scientific
facts had not yet reached a critical point. Human knowledge took centuries to
double, fact by fact. As knowledge accumulated, the rate of accumulation began
to speed up. Every answer exposes a new question. Buckminster Fuller spoke of
the Knowledge Doubling Curve which was relatively flat for centuries, then
began a slow climb, and then went into an explosive upward thrust.
By the end
of the 19th Century, knowledge was doubling once per century. By
about 1945, the rate of doubling was about every 25 years. By 1982, the rate
was about every 12-13 months. By 2020, the doubling was occurring about every
12 hours. With at least 50,000,000,000 devices now operating and with the rise
of artificial intelligence, the rate may now be in minutes.

The Greek philosopher Leucippus teaches that all matter is composed of
identical eternally existing, constantly moving particles surrounded by
nothingness between the particles. His
student, Democritus, further developed the atomic theory. Democritus taught that everything is material
and is created by combinations of eternally existing atoms.

Heraclitus, a Greek philosopher whose ideas correctly predict one of the main
concepts of the modern understanding of the nature of matter. He teaches that
solid matter is really made of fire (read this in the modern way as subatomic
particles) which is in constant motion.
