Simply put;
According to current theory, any astronomical object
is the product of collisions.
Think of two objects colliding, pulled together by gravity.
Unless they are coming straight toward each other,
there will be some spin when they meet.
This angular momentum has nowhere to go,
so the combined object spins.

That each and every thing has some spin would not require lots clarification. the alternative is that one and all the forces interior the universe coated up precisely, which seems no longer likely. by using fact in case you shove some thing right here, and a few thing else shoves it there, and the two forces do no longer line up, then the object will turn. And as quickly because it somewhat is started turning it somewhat is going to proceed doing that until another pushes end it. it somewhat is the actual regulation of conservation of angular momentum, which all actual theories obey. What does require clarification is once you detect a device of gadgets all spinning interior the same direction. so a techniques as for the no longer hitting the solar ingredient the earth is attempting to fly removed from the solar the solar is pulling with all it somewhat is could and is only able to hold the earth the place it somewhat is we could desire the solar would not weaken or get better for that count.

According to some scientists the earth started spinning when it was hit by another planet which is also when the moon was made. I suppose all the other planets spin for the same reason. Our galaxy spins because at its centre is a black hole which is sucking matter into it, this sucking motion causes the matter to spin around it the same as water draining into a plug hole.

Well, consider: The Earth was slammed by a Mars-size object early in it's history, which gave us our moon, and knocked us 23.5 degrees off-axis with our orbital plane.
Probably, the Earth was spinning prior to the collision. We see asteroids that are spinning, and from what we know about how the planets formed, it's likely that the initial spin of the whatever mass started to collect as the Earth remained.. any smaller bits of matter were simply added to the Earth's mass, our spin continued.
Then, came the collision. Immediately after the collision and up to the formation of the moon, our spin was much quicker - say, around 10 to 11 hours for complete rotation.
The moon, due to tidal effects has slowed our spin (and continues to slow it today), as it moves further away from us.

Poorcoco... has it right. The idea is that a widely dispersed cloud of particles will probably have some nonzero angular momentum by random chance. When it is widely dispersed its rate of rotation will be very small.
As it shrinks the rate of rotation will increase because the total angular momentum has to remain constant. Small compact bodies will spin up to a pretty impressive speed -- just imagine the amazing rotation rates of pulsars.

Current theory holds that the earth, sun and all of the other planets and stars not just here, but throughout the entire universe are formed when clumps of gas form in a cloud of interstellar gas and as these clumps condense through the effect of gravity. As these clumps attract the surrounding material, they start to rotate.

As quantum above said.
At some point a large object hit Earth at an angle causing us to start rotating. Now as there is nothing in our way only vacuum there is also nothing to slow us down or stop us.

First, the word is DOES, not DOSE.
Celestial bodies form out of condensing clouds of gas. These clouds have some tiny initial rotation, and as they condense they revolve faster because of conservation of angular momentum, just like a spinning skater pulling in her arms or kids leaning inward on a merry-go-round.

because God made it that way to give all sides of the earth sunshine and nightfall. Trust me that's the most sensible theory of them all.
