Actually, the earth is changing its speed. Not much its magnitude, but its direction. We are on a rotation around the axis of the earth, as well as around the sun.

In order to have the direction changed a force is indeed required. That force is gravity.

Yeah, true. I forgot about that

Well I know what I know and no amount of convoluted math is gonna change what I can figur out from commen sense!

That's why I tried to make it as simple as possible, without any equations with numbers (just explained with text).
Sorry, but I tried to make it simple. Is one equation - a rather simple one at that - really enough to warrant the phrase "convoluted math"?
Is math wrong?

Well obviously if the earth is a ball the people and water on the bottom side are gonna fall off. Not to mention how we could possibly withstand the force of being hurled through space while spinning at 1600KM/hr! Use some common sense! Think for yourself!!

The main problem is that you have an incorrect understanding of forces. Force is calculated by multiplying the mass of an object by it's acceleration. This means that if something is travelling at a constant speed, acceleration is zero, thus the force is zero.

When you say that we would feel tremendous force from the Earth spinning at 1600KM/hr, if the Earth isn't changing it's speed then you won't feel any force at all. It's like when you're in a car moving at a constant speed, it feels the same as when you're stationary. The feeling of force only occurs when you accelerate or brake.

So if we are on a sphere hurtling through space and spinning at 1600KM/hr, if that rate isn't changing we wouldn't be able to feel it. Which we don't. The speed isn't changing either because space is a vacuum, which means that there is no friction to slow the Earth's movement or spin down (space isn't a perfect vacuum, so we are actually slowing down. However it's force is negligable so it's impossible for us to feel it).
