ELI5: Why did ancient civilizations that have no connection (e.g. Incas and Egypt), all come to find gold to be valuable?

Probably because gold unlike other most other metals does not rust or tarnish and is very malleable. It is also much rarer than other metals available to them. The fact that you can make items which will not tarnish created a demand for it. This demand coupled with the short supply is why gold was valued by many civilizations and continues to be valued today. Short supply, strong demand.
