How the Internet works:

1) If the target IP X is within any of your networks, lookup X's MAC and send the packet to it directly

2) If not, find a nexthop device within your network that knows how to reach X. Look up their MAC and send the packet to nexthop.

3) Repeat til X gets it

Step 2 is done with routing table, that gets updated by various protocols so that cost is involved ( shortest path, highest bandwidth )

Basically, it's "I know a guy, who knows a guy, who knows another guy"

So this is happening in all the packets in the network every time ? If yes is there another affectionate way to do this rather than try all the devices ? .. also that’s mean that if the network has a lot of connected devices that would be slower right ?

Everyone is always asking how to find X but never how is X?

I always wondered how could just IP get a packet from point A to point B. That gives me a great scaffolding to learn more

Eventually a chain or in Better terms Linked List or may be a node with address of its adjacent nodes forming up the arrangement or topology in network terminology

‘Within any of your network’ is a lot of words and clunky to say ‘same subnet’.
