Er, no. There are really old human remains just about everywhere you look - and that's not just on the Parliamentary benches.

Stonehenge f.ex.: https://www.nature.com/articles/s41598-018-28969-8

There’s been a few interesting finds in peat bogs.

I can't think where that's been R'd from. If anyone cared, 500000 years or so seems quite old.
