Because a space suit is used to provide the human body with earth-like conditions inside the suit. Earth already has earth-like conditions, therefore we do not need suits to be on the earth. On earth, we already have an atmosphere and the proper pressure and temperature to keep the atmospheric gasses dissolved in our blood and going to our tissues.
There are places on earth when we do need a 'suit' to stay alive. Places where the temperature, atmosphere and/or pressure are not adequate to keep us functioning properly require us to wear suits. Under water would be one place. There, we need a suit to keep us warm, and a mask to keep us breathing. Another place that I can think of is on top of a high mountain. Up there, the pressure is reduced enough that we have a difficult time getting enough oxygen to dissolve into our blood. So we increase our lungs' exposure to oxygen by wearing an oxygen mask.

We have an atmosphere that keeps oxygen in and also protects us from uv rays.

What are basic requirements to construct building on mars?
there is no atmosphere so we would not be able to leave spacesuits and the gravity is not as great as it is on earth so i dont know how the buildings will stay down
Can you eat through a space suit?
No. In the past spacesuits have had food inside and all spacesuits have drinking water in them. But, neither food nor water can go through the suits when they are pressurized.
Will astronaut feel hot in their spacesuits?
No the suits are regulated to protect them from the freezing cold of space.
How much does a spce suit cost?
All NASA space suits are custom made for every astronaut and every mission; they are HIDEOUSLY expensive, in the millions of dollars. If we went into the business of making commercial spacesuits (which we will need to do within the next few years) we could probably get the cost down to $25K or so. Not cheap by any means, but affordable. We would need at least "Small", "Medium" and "Large" sizes, and perhaps a "Tall" model as well. By the time Bigelow Aerospace starts running their orbital hotel (with round-trip scheduled service via Virgin Galactic Spaceways), we'll need to have a supply of tourist-class spacesuits which can't be exceptionally expensive.
Why does the earth need wind?
The wind is a natural consequence of variable temperatures, aided in part by the Earth's rotation.
Why do you have to wear spacesuits?
No oxygen in space. We need oxygen.
Where does the astronauts get there spacesuits from?
The spacesuits of the astronauts are given by N.A.S.A.
Why should the astronauts use a spacesuits and helmet while walking in the space?
Astronauts wear spacesuits due to the absence of pressure in space. They need to maintain the pressure level on Earth by isolating themselves from actual space. For the helmets: there is no oxygen in space. Humans require oxygen to live, inhaling it through their nose and mouth. Therefore if they do not wear helmets, they will die instantly from loss of oxygen.
When were spacesuits invented?
Yesterday
What outfits do spacemen have to were in space?
spacesuits
Where is gold used in spacesuits?
On the visor
Are spacesuits comfortable?
ya man they are
What colors can spacesuits be?
Orange, white,and blue
What is the material that in spacesuits keep you warm?
they have heaters
Are spacesuits the clothes you can where in space?
No, you can wear jamies!
Are spacesuits made cheap?
No, the spacesuits that space programs put on people when they send them into space are very expensive. Prices vary by design, but they are by no means cheap.
What developments had to occur before Yuri Gagarin could orbit the earth?
Safe rocket travel, Pressurized spacesuits & capsule, Heat resistant shielding (for re-entry)
