Any more proof of those events than there is for Kwanzaa or for the existence of Zeus and his son Hercules or Odin and his son Thor?
You are free to be an unbeliever.
The interesting question is why you are consumed with undermining others' belief.
There is plenty of proof of Christ and the events of his time.
You choose not to look for them.
these are ALL proven facts.
the problem is that the internet is controlled by the Illuminati, and they want us to believe lies!
these is no limit to the evil plans of the Illuminati!
There is more historical reference to the life of Jesus than there is to Socrates, Plato, Julius Ceasar and yet I bet you believe they existed.
If you really want some proof of Jesus (which I doubt you do) read The Case For Christ by Lee Strobel.
Lee is a former atheist who was an investigative reporter years ago. He took his experience in investigating facts and applied it to the life of Jesus.
As far as the winter solstice and such, granted Christmas and Easter shanghai'd pagan holidays, but just because someone chooses to create a holiday to counter another doesn't disqualify it as a holiday. If I choose to celebrate Christmas, "I" choose what in the holiday I celebrate. Whether its the religious belief of the birth of Jesus, or its the secular following of Santa Claus. Pagans are still allowed to celebrate the winter solstice.
