Take a look at Turkey

The oldest temple in the world in Gobekli Tepe and it dates back 11,000 years. It is located in southern Turkey and it was built for the purpose of worshipping Sirius, the dog star. This one may be the oldest, bu it is not the only one in the world. There are temples all over the world that date back thousands of years and they were all built for the purpose of worship by those who built it.

Mayan, Greek, Egyptian, Buddhist, and so on, people created temples as a way to show their gods their respect and to have them rain down their plenties on those who worshipped them. Now they are a way for us to view into the past into the minds of those who left the temple behind. They are sites of wonder and amazement as their architecture surpasses that of what we thought ancients would ever be capable of.
