Did Mars lose it water to Earth in a near collision? Where did the near planet idea originate? Is it a myth?

That's a very interesting theory, I've never heard that before. However, I'm not sure how that would get rid of water on the planet, unless the magnetic forces just pulled all the water off the planet. In addition, I'm pretty sure that Mars and Earth were not binary planets, just due to how they formed.

Dust and particles orbited the Sun when our solar system was just forming, and these particles collided and combined to become the planets. All the particles were orbiting in the same direction, and by the time they were large enough to be considered planets by today's standards, I believe they would have been far enough apart to not be drawn to each other by gravitational pull.

The theory that I was taught in my astronomy classes was that Mars lost its magnetic field pretty early in its own history, and any atmosphere it may have built up by that point was then easily eroded by solar winds.

Due to the loss of the atmosphere (and therefore atmospheric pressure and considerable warmth), water could no longer exist outside of an ice form on the surface. There's more information (and more details) about this process at the link in my sources. Of course, if this is no longer the theory in mainstream astronomy, then... okay.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
