I want an earth-sized planet with a moon-sized moon to both have complex, possibly intelligent, life. First, isWould it reasonable to assume thatbe more realistic for life could thrive on a moon of that size? And second, should live evolveto develop separately on both bodies,each body or onfor life to transfer from one and then be transferred to the other through panspermia(if so, which one first)? Is there anything else I should take into consideration? Thanks for your help :)
