I like your chart better, it has better links to sources.Can you posts links to graphs like that?
The best link I found was :
Global temperatures over last 24,000 years show today's warming 'unprecedented' but that is not NASA
There is pretty good science available today through proxies that have enabled us to do so not only on our own planet, but also others.There is no conclusive way to measure temperature prior to 1900. It's an estimate from a model. Models are nothing but assumption generators relaying upon tangent information.
It's amazing people think we can tell the temperature of the earth 5000 years ago.

Fossilized pollen is one way of estimating prehistoric temperatures.
Ancient Pollen Offers Clues to How Plants Adapted to Climate Change in the Past — and Potentially the Future
A new study finds that plants around the world moved poleward during a dynamic period of rising temperatures 56 million years agowww.smithsonianmag.com
