Of course it has. In fact space has been around for as long as the universe has been in existence. Look at space as a body of water; it has length, width, and depth. Now put a trampoline over the surface. This is space-time. Everything in existence sits on this "trampoline" as matter with mass, pressing down no the surface. Now take out the space (water) and nothing is there to support time, the (trampoline). So without space we wouldn't have time, movement, or any matter or mass today. Nothing would exist. So yes, Earth has been in space indefinitely and always will be.
Your question does not make any sense. The Earth and the Moon stay the same size and are always in Space.
No, the location is constantly changing.
The Earth needs layers because the earth is cold, some parts of on on top of it have heat but the Earth is always cold because of cold Space. It needs heat inside.
Yes earth is in space
The Earth Space with has because the plans..
There are spatial dimensions on Earth. So space ison Earth.!
Space is different from earth because space has no gravitation, earth has gravitation
How dense is space? What is the chemical makeup of space? Is our Sun new or old? How big is space? How much does space weigh? Where is space? Is space always dark? Is there precipitation in space? Can sound travel in space? Are there UFO's in space, or just here on Earth? Are there colors in space? Is space three dimensional? Does the theory of relativity apply in space? How far away could you see a flashlight in space? Is space new or old? How old is space? What kind of things have come close to the Earth? (see Spaceweather.com asteroid encounters)
Not in outer space; but it does rain on Earth and Earth is in space so in a sense it does.
Gravity is one of the most obvious answers. Weather would be another.
No. Pressure could be simplified to mean the "space between particles" and because gravity is always pulling those particles towards the earth, the further away from the earth you go, the less air particles there are and consiquently the more space there is.
Earth does have air while the space does not have air.
