Most have urges and desires. Most want to have pleasant experiences (the upper levels of Maslow's pyramid) and mitigate unpleasant ones (the base).What's stopping humans from doing nothing and becoming nothing ?
Then they won't do them.what if someone feels that life is better without doing those things [have friends, show empathy, help people]?
It evolved through a series of undirected genetic changes and was selected by nature for obvious reasons. Those with the best survival instincts will live to reproduce more than those lacking them.Why does the survival instinct exist ?
We observe biological evolution to occur in populations over generations and have good fossil and genetic evidence that the tree of life has been evolving over geological time.How do you know that evolution is true ?
Everything evolves. Galaxies, stars, planets, and mountains evolve, just not biologically. Elements evolve in stars. Books yellow and their pages fade. Iron rusts. This is material evolution.
Individuals evolve as they grow, develop, learn, and age. This is biological evolution also, but not in the Darwinian sense.
And populations evolve, which IS biological evolution in the Darwinian sense.
Cultures evolve. Technology evolves. Languages evolve. Religions evolve. Everything evolves.
