Humans are slaves to a race that has populated earth for billions of years

Just a thought here... I have looked up at the stars and studied ufo's for a long time and I have come to believe that there is a race of beings that have lived on Earth much longer than human beings have. Maybe this race even made human beings to be their slaves. Our lives serve no function as to mine the earth and make the 1% richer everyday. There is some interesting work from a researcher in South Africa studying 150,000 year old ruins in his country. Supposedly human beings started becoming civilized about 10,000 years ago but the Globleki tepe really changes things. How could their be ruins built by intelligent people that are that old? I believe we humans are nothing but slaves on this planet serving beings that have been here for millions or billions of years. The earth is 4.5 billion years old but it took us humans 400 years to go from dumping our shit out the window in the Middle Ages to being able to post this article from an iPhone in my hands. Even if someone from the 1960's saw the technology we have today they would assume is alien technology. Any thoughts people?
