Johanne, you and Nick are classic ufools
You would not know 'scientific information' if it bit you on the nose.
You have nothing at all you can produce in any form except fictional that relates to flying saucers or cigars making 'impossible manuvers'.
Zip. Nada.
And Nick even posting such bullshit as that alleged photo as if it were to be accepted as a credible evidence of anything other than a poorly doctored photojoke only shows the low price of real estate between his ears.
There is even less evidence for eti visiting this planet than there is for your amazingly ignorant claims about radioisotopic heating of the atmosphere.
IOW, none at all.
