Who exactly claims that to?
I've read repeatedly that if any of the four forces (gravity, electromagnetism, and the strong and weak nuclear forces) were slightly different, or if even just the force of gravity were slightly different, then life as we know it couldn't have happened.
I have no idea if that's true. I do know I've heard it a lot.
