Druid religion

I see in the internet where Druidy is now accepted as modern day religion. This will give them Tax breaks in England. Are we going backward in time ? How many more old time Pagan religions will come about. Modern christianity from what I can read is a conversion of old time Greek and Roman pagan religion, or so I have been told or figured out for myself. I do not know whether this is true but it is thought that come about because of the originating rituals. Will the old time Roman and Greek pagan Religion come back in force. How many people have studied Plato where he asked many question of people and from what I gather he was after the unknow god singular in purpose. According to the studies- Plate killed himself over the religious attitude that became the I believe Christian belief. I of course do not know whether this is true but there is no way we can go back like that TV show where this man and young person went back in time and investigated what when on. all this reasoning has come from the Idea that Druidy is now a recognized Religion in Great Britain. Isn't that wonderful what studying History brings about the different ideas.
