Why did the spanish have guns but the Inca did not?

The Spanish had guns due to their advanced Metallurgy and military technology developed over centuries, which included the production of firearms. In contrast, the Inca civilization had not developed gunpowder weapons and relied on traditional weapons like spears and slings. The Spanish also had access to resources and knowledge from Europe, which facilitated the creation of firearms, while the Inca were focused on agriculture and infrastructure. This technological disparity contributed significantly to the Spanish conquest of the Inca Empire.
