Can flesh and blood enter into heaven?

flesh and blood cannot enter heaven, Jesus said so...but flesh and bone can enter. blood is the only thing thats forbidden throughout The Bible. jesus had lost all his blood on the cross and was resurrected with no blood in his body. his disciples touched him, felt him and even saw his scars so he definately was not a spirit or in spirit form. the very condition that Adam and Eve were before they sinned, they were flesh and bones. there is certainly no way Elijah went to heaven in flesh and blood, remember there are three heavens mentioned in the bible...so elijah might have assended to heaven but not the third heaven where God is. Jesus also said that no man had ascended to heaven, he knew because he came from heaven...the third heaven Where God is
