Philosopher who differentiated two fundamental fields of social studies, history and geography, was "Immanuel Kant".

The philosophy of Immanuel Kant (1724– 1804) can be isolated into two noteworthy branches. His theoretical philosophy, which incorporates power, depends on the normal comprehension of the idea of nature. The second, his political philosophy, involving morals and political logic, depends on the idea of opportunity. Both of these branches have been immensely powerful in the resulting history of rationality.

giant impact theory - the moon was formed from the collision between earth and another mars-sized body.

colliding planetesimals hypothesis - the moon was formed from the same cloud of material as earth.

capture hypothesis - the moon was locked into orbit by earths gravity as it was passing by it.

accretion hypothesis - the moon was formed from collisions and combining of planetesimals.

i think this is right, if not and you know better let me know.
