Are spiderman and Batman really the same person?

This comes about due to multiple reasons, The first they look alike, they both have brown hair and have similar suits

They both lost their parents, which I know is just small a chance its the same but, heres the big evidence

Batman could have gotten his money from the sponsorship deals that he got from being Spiderman. The spidery powers could have been lost over time, causing him to train hard and become batman.
