Blender Render 8

I discovered free object assets online. here you can see I'm just playing around with scale and different things from the assets I downloaded.

I was basing this one on the thoughts of 'After Everything, What Will Exist' to answer the question. Not much. maybe 10000 years still have big structures, but most thing would've collapsed. 1 million years, probably nothing. but that all depends what happens here.
