Doesn't anyone give serious answers?
American spaceships land in the water, braking with parachutes. Soviet spacecraft have a pole beneath the bottom of the craft. When it touches earth it fires the retrorockets, creating a blast crater. Braking is very sudden, but it works.
The space shuttle, as noted, glides to earth, sort of. Call it a carefully controlled fall.
The Mars Rovers used a combination of parachutes and big, inflated balloons. They came in at an angle and bounced a bit. The Genesis mission was to come down by parachute and the be plucked out of the sky by a helicopter. The chute did not properly deploy, and it smacked into the desert floor.
As for alien spaceships, we have never verified the existence of one. They might use any of a wide variety of techniques, possibly some we have not yet dreamed of.

For the early spacecraft only a small section carrying the crewmembers retruned to Earth, the rest of the spacecraft being left in orbit or burning up in the atmosphere as it re-entered. The early NASA spacecraft (Mercury, Gemini and Apollo) descended under parachutes after re-entry and made a spalshdown in the ocean, where the crew were picked up by naval recovery ships and helicopters. The first Russian spacecraft, Vostok, also descended on a parachute, but it did not land in the ocean. It made a landing on land, but the parachute could not slow the capsule down enough to avoid injuring the pilot, so he ejected some miles up and came down on his own parachute. The later Russian spacecraft, Voskhod and Soyuz, used a small rocket pack suspended under the parachute to further slow the capsule just before touchdown, enabling the crew to remain in the capsule throughout re-entry and landing.
The space shuttle glides down to a landing on a runway, touching down on small wheels a lot like an ordinary aircraft.
The only other spacecraft to make any kind of landing was the Apollo lunar module that touched down on the Moon. It came down on a rocket engine that slowed its descent to allow a controlled landing.
The only one of those that requires a special platform is the shuttle, landing as it does on a runway, though in theory it can land on any large flat area. It does have to be flat though. Dry lake beds are a good substitute if a runway cannot be reached.

Hard to tell how spaceships can land cause THERE ARENT ANY!!!!
But if you mean space shuttle, they land by entering the atmosphere backside first and front pointed up.
Then its like landing a plane after.
