There are MANY theories but so far they are all just "Theories". Some of these seem to make sense and seem to be supported by various such theories but to-date NONE have been proven to be absolutely correct.
And how come all of our planets are so d@mn ROUND? Why are they all perfectly spherical? Is that because of our Suns gravitational pull?
It is due almost primarily due to GRAVITY. You can say erosion but that is just a product of GRAVITY. You can say it is it is due to the spin but then again that is due to GRAVITY.
(Bet you didnt know a hayseed like me could even SPELL spherical, LOL!)
It just so happens that I personally know many hayseeds. Some even consider me one such individual - hayseed (that is).
And does the Sun have a name? Does the Moon have a name?
The SUN is called "SOL" or just "The Sun". In other languages and religions they gave it different names - to many to waste my time enumerating.
The MOON is called "The Moon" or "Luna". AGAIN - Different languages and different religions gave it different names.
Thank you all for the enlightenment. This is one interesting area I need to study up on!
