New Kicad User - Lost in PCB layout step - How? Why?

I am using KICAD for the first time as I have a desire to build a strobe flash circuit. I’ve gotten schematic built and completed ERC. But the whole layout 'THING" is very confusing to me … Is it analogous to the schematic build … place component, make wire connections, test?

In PCB layout, Are we supposed to address the spaghetti wire lines? Why do they jump around as you move components position on the board. And trace routing… wow.

Is there a good detailed tutorial on this part of the design process? Help!

Did you watch the routing tutorial from our youtube channel : https://www.youtube.com/watch?v=9HpYpP2L10A ?
