I don't know why you got downvoted but I couldn't find anything helpful regarding your question. I found some references to the fact that mars and earth have ~24hr days but no explanation as to why they are so similar. Mars also rotates (on its axis) the opposite direction of Earth which I found interesting. So many questions about our little local solar neighborhood, so few answers!
