Taking a quick look at Wikipedia, the Julian calendar was used by much of the world from the time of Julius Caesar until supplanted by the Gregorian calendar in the 1500's, and at one time its beginning was defined as 753 BC with the founding of Rome by Romulus and Remus. Their father was the god Mars. Back in the days of the Roman Empire if you had said that Romulus and Remus never existed many would have replied, "Then it's the greatest hoax of all time."
Time passes by, but some things never change. There will always be believers of myth.
Evidence allows us to distinguish between what is possibly true and what is actually true. This thread is about fulfilled prophecy rather than the existence of Jesus, but the need for evidence is the same.
