No no. Jesus was born on 0AD. This kid was born on 2AD. Jesus would have been 2 years old, so he hadn't yet died.
Whats more concerning, is this is being posted by one of the kids parents. Which means THEY were born sometime in BCE. Which means they were alive and old enough to have kids when Jesus was born.
WHY ARE THEY NOT REVEALING THEIR TRICKS OF IMMORTALITY????
And also, why are they threatening their kids life?
A small correction and „fun fact“: there is no year zero. 1 BC is followed by 1 AD. Consequently things like the turn of the millennium happen a year after we celebrate them. But people found that weird.
The disturbing answer to both of your questions is drinking blood of children keeps you young. It's all about adrenochrome and you can but shouldn't google it
