Maybe?

I have a theory, what if time actually does go by... আপনি may be thinking "you're crazy" but let's think about it so let's say Peter Pan is 12 and 1 সেকেন্ড goes দ্বারা for everyday here on earth it would take 60 days just to reach a full মিনিট now × 365 (a year) দ্বারা 86400 (the time of সেকেন্ড in a দিন that would be equal to 31536000 (the time of সেকেন্ড in a year) so now × 31536000 দ্বারা 60 and আপনি would get 1892160000 (how many সেকেন্ড in a বছর for Neverland Time) so in 50 Never land years that would be equal to 94608000000 years in Earth Time so peter would still be 12 in 50 of our years, so what I'm meaning about this is Peter does age just time is way slower than the time that we have.

Welp that's just my theory!
