Christians - What would you do if it were discovered Jesus never existed?

[Kingpin]

i highly doubt jesus existed for many reasosn. Also the fact said person "died" and came back to life is also very questionable.
I mean really he died and came back to life people back then never heard of weak pulse or shallow breath so the guy more than likely if he had
existed was pretty much alive so for those 3 days he was "dead" he was pretty fucked up and resting up then goes to his people talks to them
and leaves walking into desert to go fuck off.

Do you really think the wounds he would have endured from the lashings and crucifixion would "recover" in three days time?  And how could he recover being sealed in a tomb alone for three days?  I don't see how you find that logical.  I know if I had a spear thrust in to my side and somehow lived and was locked in a cell alone for three days, not only would the hole still be there, but probably festered and infected and sure as hell wouldn't be able to walk around like all was well.
