As usual your post is a complete idiocy, Georgy Boi !
Ever thought about the concentration in all types of acids to erode the
intrusive & extrusive rocks, and clear completely at that the quartz
crystal as well as the feldspars ... and in fact reduce all constituents of
those complex rock structures to their most elementary elements : sand,
clay, heavy sands ! I will give you that answer : Sulphuric; Nitric then
Chloridric Acids falling in constant rains, but of course not on our present
orbit .... indeed we are born from the Sun and beyond Pluto is our
permanent aim indeed !
Of course you bloody fool as well as your imbecile alleged science of
Gogology completely ignore the right sequence ... in clear the drift of that
planet on the Sun Equatorial plane within an anisotropy and anisobaric
Cosmic environment. ...or where from we come and where we are heading too !
Please stop that Creationist Accretion miracle and Big Bang mystery ..such
sectarian/ religious beliefs are so sickening on an alleged scientific new
group
I have already told you harebrained Ron Yates that Venus & Mercury before
are mileage mark where we come from, and Mars is were we are heading too
now !!!!
Unable to learn, hey Dork ?
By the way, is it true that you believe still in Glaaaaciationzzz, Yates
boi ? ... as well as Continental Rafting ?
I bet my bottom dollar you still do !
You want to see it mate ?
Tell us I won then !
... as for a date when the last Dinosaurs died it was a mere 11700 years
ago... that same age as that monkey called Lucie by some clueless dogmatic
Cleric ... that same age for the whole Alpine Orogenesis too !!!
Nom de Dieu, mais c'est pas possible !
Who needs comics with you around, Mate ?
