|t is said that hydrogen & helium is present over the space everywhere.
But it is also said that space is vacuum.
please give me a clear explanation

'Vacuum' is a relative term. Near a Star there's probably an atom of hydrogen or helium (or something) every few cm. In interstellar space (between the stars) that's probably more like an atom of something every few meters (unless you're in a dust cloud or a gas cloud). And in intergalactic space (between the Galaxies) it's probably more like an atom every km or so.
But, compared to our atmosphere, they're all vacuums.

there are three basic things 1. LAND 2. WATER OR THE SEA 3. THE SPACE ATMOSPHERE.
According to your question i am limiting my self to atmosphere. but to give a rief idea the sea and land has various layers in them, in land you have various layers where you get different metals and ores.
then the sea has various layers which has different depth and you find the flora and fauna underwater according to the depth.
similarly the atmosphere is also divided into many layers, atmosphere the layer just above the sea level, then stratosphere, then lithosphere, there ionosphere where all the wireless signal are transmitted.
Then you have the exosphere, where you start getting traces of hydrogen and helium
when you go beyond these there is space which doesnt have anything not even air and its called vaccum.
May be you can say the black holes exist there.

space is a false vacuum. its near impossible to get a perfect vacuum. its mostly filled with hydrogen and helium at extremely low densities. something like 1 atom per cubic cm.
and to the first guy. Ether was discarded decades ago...wtf are u doin?

Well you are right. A perfect Vacuum is impossible. On Earth we create a vacuum by removing all the air from a close environnement. In Space it's pretty much the same thing, there is no air, but there's some other elements (like the one you described).

Space is filled with the whole universe or the universe is in the space.

True space was considered as vacuum , but new findings and theories suggest that space is not as empty as it looks but is filled with dark matter (whose definition scientists are clear about).

no air in area. If there develop into we would be waiting to stay in area. And in case you propose if there is any sort of gas then no. properly particular yet its basically a tiny tiny tiny quantity. so small that it isnt even counted

Its vaccum, but the reason why you dont get sucked up by that vaccum is that you need to have some great mass there to suck you in, so planets have gravity and vaccum helps them to suck any object caught in that gravity.
