I am an ordinary person so the standards of evidence for my existence are very low. Even a minimum historical Jesus is an extraordinary claim that requires a precise sequence of events with multiple unrelated groups acting unusually. This is a big claim and needs more evidence.
Additionally if you asked me to tell my life story I can bring forth evidence of my claims. I have a birth certificate, a license, a diploma, a marriage license, utility bills, etc. So here I am a very insignificant person in human history and I can produce mountains of evidence for my existence. While your Messiah we only know about because of liars writing decades citing dreams as their source.
I will save you some time. All the Gospel writers were copying Mark and Mark was coping Elijiah and Paul. And Paul was having weird dreams about a celestial being. A copy of a copy of a copy with no original.
