There is no way to prove or disprove a claim such as the ones made for Jesus in the New Testament.
In my opinion, the fact that there are contradictions between the gospels, as well as contradictions between alleged events in the gospels and the historical record (such as the fact that the census in the nativity story of Luke never happened) makes the texts unreliable.
How does your “opinion” suddenly transform into a “fact?”
There are no logical contradictions between the Gospels. There may be difficult to reconcile accounts, but those are far from being contradictions.
You do understand that a contradiction means logically impossible for both to be true, correct? And not some attenuated “definition" of “contradiction” such as: “I don’t like what I hear?” That would be a “disagreement” not a “contradiction.” See how that works?
You will need to provide proof of your claim that the census under Quirinius NEVER happened before that kind of bald assertion suddenly and magically transforms itself into a “proof.” Again, you seem to be conflating your opinion with facts and your assertions with proofs, as if merely convincing yourself is sufficient to make the case.
At best, the full story lies buried somewhere in the historical record and we cannot draw the conclusion that Luke (or some other Gospel author) is simply mistaken – it may very well be that Luke had access to details that we do not. Since he lived at the time and we are 2000 years removed, my money is on Luke.
A good analysis is here:

Summary in the Prospects section:
Here we may gather up the evidence to present a composite picture: (1) Luke’s census is not a historical impossibility. Rather at all points, historical analogies can be drawn. (2) Quirinius was not the official governor of Syria at the time of Jesus’ birth. The Syrian records and the current accepted chronology of Jesus’ life simply prevent this conclusion. However, Quirinius’s personal chronology is not fully known, particularly around the years of Jesus’ birth. Thus, it is not impossible that he held another office at the time which Luke appropriately describes with (h[gemoneuontoj thj Suriaj) hegmoneuontos tēs Surias, a description as we saw which could also appropriately describe the office from which he took his well-known census. In short, it is most likely under this otherwise unattested office that Quirinius officiated over what Luke describes. To say more would go beyond the present evidence; to say otherwise, would, as we saw, strain the syntax. As such,** I. Howard Marshall is probably right when he suggests that Luke’s full vindication lies buried somewhere, waiting to be unearthed.
Until then, Luke’s historiographical track record (well-documented in other places) and the implausibility of such a monumental miscalculation, especially considering his method of and purpose for writing (cf. Luke 1:1–4), should forestall the rather premature conclusions noted initially. Moreover, for those of us with a high view of Scripture, the fact that Luke’s record is indeed part of Scripture suggests that these conclusions are not only premature but are, in the end, simply wrong. Further evidence will only demonstrate this more conclusively.
Personally, I’ll go with the best that scholars have to offer (the bold-faced comment of Howard Marshall above) and let the full story reveal itself in due time. Any “conclusions" for the moment, even by heartfelt atheists wishing to discuss the matter behind some pious atheistic agenda or other, ought to be viewed with a measure of skepticism.
Unfortunately some of the “hardened skeptics” on this forum are not sufficiently “hardened" to be skeptical of their own views with the same measure of skepticism they demonstrate vis a vis the views they are hardened against. Right, Kate?
