Maybe?

I have a theory, what if time actually does go by... anda may be thinking "you're crazy" but let's think about it so let's say Peter Pan is 12 and 1 saat goes sejak for everyday here on earth it would take 60 days just to reach a full minit now × 365 (a year) sejak 86400 (the time of saat in a hari that would be equal to 31536000 (the time of saat in a year) so now × 31536000 sejak 60 and anda would get 1892160000 (how many saat in a tahun 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!
