If you look at the universe and study the universe, what you find is that there is no evidence that we need anything other than the laws of physics and the other laws of science to explain everything we see. There's absolutely no evidence that we need any supernatural hand of god. -- Lawrence Krauss, World-Renowned Physicist
There is probably no other notion in any field of science that has been as extensively tested and as thoroughly corroborated as the evolutionary origin of living organisms. -- Encyclopedia Britannica
FAITH. No one word personifies the absolute worst and most wicked properties of religion better than that. Faith is mind-rot. It’s the poison that destroys critical thinking, undermines evidence, and leads people into lives dedicated to absurdity. It’s a parasite regarded as a virtue. -- PZ Myers
Religion is the antithesis of science, an anesthetic for the mind that disables critical thought and encourages the acceptance of inanity as fact, and wishful thinking as evidence. -- PZ Myers

What do you think of the concept 'Survival of the fittest'?

"What do you think of the concept 'Survival of the fittest'?" 

The cheetah has evolved to run fast to catch prey. The prey have evolved to run fast to avoid becoming a cheetah's lunch. It's an evolutionary arms race. The fittest survive. Their genes are passed on to the next generation. 

Another example: The gradual increase in the brain size of human ancestors made it possible for them to survive in their hostile environment. 

Another example: The evolution of shells on turtles allowed them to survive attacks in the sea from above or below.
