Dude you should really do some objectivestuffy into thesubject before declaring the battle won a long time ago. For one Krauss is being massively dishonest when he says the universe came fromtoting. He's present a Vacuum Fluctuation Model which presupposes the existence of space, time, energy, laws of physics, and the quantum vacuum, none of which are "nothing". His theory imposes that 4/5 of the univer pre-exists matter and work to create it.
Secondly if you honestly are going to hold to the Jesus myth theory then you obviously haven't bothered to even google this subject before hopping onto an apologetics board and mashing both caps lock and exclamation points. There's more than half a dozen non-Biblical ancient historians who speak about Jesus such as Pliny the Younger, Josephus, the Babylonian Talmud, Mara Bar Sarpion, and others. Anyone who claims Jesus never existed is either uneducated on the matter, or deliberately presenting misinformation.
Also try to avoid presenting the case that somehow these arguments were defeated in the past. They really haven't been defeated, and typically the only people I'm quoted as having done so are vitriolic YouTube atheists who don't have a real grasp on the subject. Thunderfoot, or Amazingatheist as examples.
If you've got questions there's a bunch of people who'd love to answer them here, but if you're going to pre-maturely declare victory off misinformation I'm going to have to suggest you study more into the subject.
