We, the people of science will believe only if it is proved scientifically. But many things which are written in ancient texts prove to be correct when the humans discover it only recently.
For example, the question whether the earth is flat or round was a big question. Those who made the discovery had to sacrifice their life by the attack of non-believers. But later it was proved that earth is round.
Just go through Hindu religious texts. There is an Avatara of Lord Vishnu called Varaha. Varaha is carrying the sphere of earth lifted on its tusks. How is it possible that the ancient people knew that the earth is round?
There is no answer. But only one thing is clear: There are many things which are not yet discovered by the scintific community, but some of such things could already be there discovered by ancient people.
