[Grammar] Is these three sentences right?

[DSoldier]

All young have car
Every young has car

There is dirt over all


A friend of mine asked me if these 3 sentences are right.
In my opinion, the first two are wrong, but I'm not able to explain why. I just feel that something is missing.

As far as I know, the third one is a incomplete sentence. It doesn't explain WHERE the dirt is.

So guys, can any of you people help me with this?

Thank you all in advance.. x)

Hello

All young have a car.
Every young has a car.
There is dirt over all.

I believe they are okay now.
Let's see what the other members will say ;-)

Cheers!

All young have car
All young people have a car.

Every young has car
Every young person has a car.

There is dirt over all
There is dirt over everything! ("all" doesn't work)
There is dirt over all my clothes. OK

Be careful when using adjectives as nouns. In most cases, they only make sense with the definite article:
"The young have poor manners."
"The young like driving fast cars."
But it's still far more common to say "Young people ..."
