Go back to your old physics textbook.

You mean, the one that says that if you shoot at something and miss the projectile never lands?

Or the one that says if you shoot a rifle in an upward trajectory without hitting anything the bullet reaches escape velocity and ends up in outer space?

No; the one that postulates that a bullet, fired straight up, will, upon it’s return to earth, will be traveling the same speed at impact as when it left the barrel.
