Our minds have evolved to measures that pass the years although it seems a little credible in the last 100 years the human being has evolved in the technological, scientific, astrophysical field, etc ... than in millions of years ago.

Previously he asked me this question because the human being did not evolve technologically, if we have the power to do so.

The answer to my question was the church, believe it or not, the church in ancient times did not like the innovative so to speak if you experimented with chemicals to make medicine they classified you as a witch or a sorcerer and you were executed as a heretic, the fear of church at that time and immense.

Currently as the world population has grown the church lost power as the years passed, and more futuristic visionaries came out to change the world.
