Some researchers believe that dreams are just unimportant by-products of neural firings during sleep. they support the what theory

Activation Synthesis Hypothesis

Explanation:

Researchers who believe this most likely support the Activation-Synthesis Hypothesis. This is a neurological and biological theory of dreams. The theory states that the chemicals that impact the brainstem change as the body and brain cycles go from day to night. As these chemicals change, they trigger the brain, leading it to activate memories that come to the surface during REM sleep.

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.
