ELI5: Why is it "Ladies and Gentlemen" and "Boys and Girls"? Is there a reason for the order and the difference in order when addressing different ages?

They're called frozen binomials; like how we say "pots and pans" not "pans and pots".

It has to do with syllables (smallest to largest), complexity of the word, and what just rolls off the tongue easiest.

Some argue a gender bias, but for every "man and woman" binomial there is an "aunt and uncle"; for every "boys and girls" there is a "mum and dad".
