@alwaysstranger A theory can't be as proven as a phenomenon. Also, Evolution is quite arguably much harder to accept than wave theory of sound.

@alwaysstranger Gravity is not a "scientific theory". Gravity is phenomenon observed between any 2 or more set of bodies in space. It is now explained by the general theory of relativity credited to Albert Einstein. Evolution on the other hand is theory which tries to explain the origin of all the living popularly through natural selection credited to Charles Darwin
