I didn't contradict myself at all, you mistake a conceptual theory for a scientific one. They are very different things. A complex being like myself is the result of the six main elements of life, its the result of billions of years of evolution. If you say, "there is a higher power", its your job to prove that the power you talk about [i]does exist.[/i] Yes, if gravity were stronger, life on Earth as it is wouldn't exist. We would be too weak too combat the stronger pressures on our bodies. However, that doesn't mean other life wouldn't exist. A planet with higher gravity would have life adapted to it. Life on that planet would evolve to have stronger bones and muscles to combat the stronger pull.
