What if jesus was an illusion ?

All of this space age tech they have, they reckon they could use the sky as a screen and use 3D holographic images, so what stops them doing it thousands of years ago, then breaking it all up in the history books ? Then rewarding people for " inventing " things they already knew about ? just a thought, so dont attack me with your bible quotes, as you Rose Cross fellas love to do, sorry , didnt you know your religion stems from a sun worshiping bunch of opium addicts ? oh well, thought id.........let you knoooooooow ......... :)
