Question

Why is the earth tilted ?
Any one knows,
I know​

Answer 1

Answer:

Scientists estimate that Earth suffered around 10 of these giant collisions. ... Today, instead of rotating upright, the Earth's axis is tilted 23.5 degrees. The angle varies a little over time, but the gravitational pull of the moon prevents it from shifting by more than a degree or so. This tilt is what gives us seasons.
