I believe in GOD and believe in all whether it is Ram, Christ, Allah, Buddha, Mahavir Or Gurus, Or any other names i might have missed. I dont question whether they existed or not. But for people questioning Ram have to then Question existence of others as well. For Questioning Ram i could same way ask what proof is there of christ existing. Did they find his remains, Did they do a Test to prove it was christ body, all we have is accounts from bibble etc, same as we have accounts of ram from ramayana and other books of hindus? Rest Ram Sethu is a place which could be made a tourisst destination and told to people that this is where Ram's Bridge mythologically existed and is it not a big coincidence that historical accounts match the exact site of where it was supposed to be built by Ram
