Virgin births exist in nature. There are entire species of lizards that are only composed of females, for example the mourning gecko lepidodactylus lugubris only reproduces via virgin birth.
Due to how parthogenesis works, individuals born through virgin births are always clones of the mother. Thus they are all females.
If (big if) Jesus existed and IF (even bigger if) he was conceived through a virgin birth, he therefore must have been biologically female since there were no male chromosomes involved in his conception. Hence, Jesus sex must have been female but his gender was male (he/him pronouns)… ergo he was a trans man.
If Jesus existed and was a biological male, he could not have been conceived through a virgin birth, the best explanation then is that either a) Mary had sex with Joseph, but then why the virgin birth story? Or b) Mary was an adulterer who concocted the “virgin birth” story to hide her adultery from Joseph.
Since explanation a) falls flat on it’s face, we are left with either 1) trans man or 2) Mary the adulterer.
Edit: correcting spelling mistakes
Scholars unanimously agree that Jesus existed, was baptised and crucified. His followers had reason to believe that He rose from the dead as well.
You also left out explanation 0, which is that Jesus was conceived via the Holy Spirit. Jesus did have a Father - God. He is God from God. Joseph was also visited by an angel and I think we could probably take it as fact that they didn’t divorce (as we have records of Jesus being referred to a boy of Joseph) So no, this can’t cause a crisis of faith for a believer.
Miracles are called miracles for a reason- you are right that a virgin cannot give birth to a male without divine intervention (except from artificial insemination)
“Miracles” are only compelling to people who already believe.
They’re utterly unconvincing to anyone not indoctrinated, as proven by the fact that you don’t believe in Hindu, Buddhist, Mormon, or Muslim miracle accounts.
Why did God create a bespoke Y chromosome just for Jesus? Why couldn’t Jesus have been born female? What would that change?
