We all know Goku is above Superman. Now, the real question... Goku Vs. Dr. Manhattan (from Watchmen) Who wins?

Dr. Manhattan is virtually invincible and immortal, and I don't think Goku could beat superman. What arguement do you have to back up goku dominating superman. I mean goku is super fast superman, super fast/goku can destroy a mountain with a ki blast, superman can cut whole planets in half with his heat vision/ both a never give up and both can become as strong as they want. superman can literally fly into sun a come out not weaker but stronger, goku cannot. Bacically after super saiyan 4 goku is done getting stronger. The longer superman live the stronger he gets and superman being kryptonian has a life span that far supes human or saiyan life spans.
