Is it ever explained how skaianet is created? Like it seems that there is a connection between the Harley's and Lalonde's having some hand in the different branches of skaianet, but is it just natural discovery or do they find something that looks ancient but has all of this advanced stuff to it?

Skaianet is Grandpa Harley’s company, he finds the Frog Temple and uses Skaianet to extract the code for SBURB and distribute it as a game in a world-wide release. Mom works for Skaianet or at the very least a branch of it. Dad’s involvement with the company is dubious at best, but it could be plausible. We have no idea how Bro knows any of the stuff he knows, but he may also be somehow linked to it.
