Earth and Mars have never collided. They are two separate planets in our solar system that orbit the Sun.
It's called accretion.
A meteor hit the earth in the mesozic era
Meteorite bombardment refers to the intense period in the early history of the solar system when a large number of meteorites and other space debris collided with planets and moons. This bombardment played a crucial role in shaping the surfaces of celestial bodies, including the Earth, and influenced the evolution of their atmospheres.
We believe that the proto-Earth, very early in the formation of our solar system, probably collided with another planet, one that might have been as large as Mars. The collision probably entirely re-formed the resultant Earth, and that the heavy metallic cores of both planets merged. Debris blasted into space by the collision probably coalesced to form the Moon.

The planet Earth
Scientists believe that the water on earth came from icy comets that collided with the planet. This would have mainly happened billions of years ago when the earth was still quite young, and when bombardment from such bodies was more frequent.
The dominant theory of the origin of the moon is the Giant Impact Hypothesis. This theory posits that a Mars-sized body collided with Earth during the early formation of the solar system, ejecting debris that eventually coalesced to form the moon.

The solar system
No. The moon formed after a planet-sized object collided with Earth.
