Evolution is the basic purpose of human life. We must continuously evolve our thoughts as we've been doing knowingly or unknowingly, so that one day man could understand the truth behind this otherwise confusing creation of God.
What we think is what we do, and what we keep doing is what we become. So, the power of great thoughts can change this world.
Evolution is sometimes confused by some people as competition. Yes, there is competition among humans but that should be only for who gets what thing. The competition among humans should just the criteria for distributing earthly resources as per capability and effort.
Animals compete by natural selection, i.e.physically but man evolves by knowledge, i.e.mentally.Man is physically weaker than other species.
Wisdom is the real power of man so he should use it correctly.
