Are you kidding me bones are created after ossification and everythign starts with liquid and ends in solid even in emybryo at no stage bone precedes flesh The process is called ossfication.. I think you need to inquire little more.. there is no doubt on that in scintifc community and this is even logical things star from liquid then semi-solid and then solild.. Trust me if Dr Naik avoids this question then there is nothign wrong in the question his polemical gymansium has not found any explanation for this yet..
