Multiple “water bodies” found under surface of Mars

[radio times]

Interesting points and thanks for your hard work. Enough is known about the young sun not being young anymore and destroying the habitat's of Mars and Venus. I don't think ancient man had any knowledge or access to nuclear tech, over the last 150 years man has 'advanced' at hyper speed to it's past. Oppenheimer etc was blue sky thinking. In the period of the great bombardment, when in addition to millions of meteor strikes all over the joint and a planet merging with us creating the moon, 'nuclear' material ( radium especially) must have been in a whirl and placed hither and thither. That's my belief. We were a bunch of dullards before the blighy Industrial revolution kick started the modern age. Painting and literature excepted.
