Why is a mole 6.022*10^23?

Question

We all know Avogadro’s number as 6.022*10^23 but why is that number significant? Why didn’t he choose something more round like 1*10^23 or something to that effect? What is the real world significance of 6.022*10^23?

I like how an ELI5 starts with “we all know <insert complex number most people never heard of>”
