New testament was written well after the fact by people with political agendas.
With Luke commonly described as post dating Matthew and Mark and written at a similar time to Acts which does not record the destruction of the temple in AD64 you've got the Gospel accounts written well within 30 years of Jesus life. In terms of ancient documentation that's huge. Those that have researched the subject know this. They also know the fallacy of the 'political' argument.
By all means choose not to believe it but at least base that reasoning on sound research.
