What is the atom more abundant of the Universe

And for sure is the hydrogen, the hydrogen is in the air that we breath that is a mixture of gases like nitrogen and oxygen, the hydrogen is in the formula of the water that we drink the water is H₂O, that is two atoms of hydrogen for each oxygen, and also the hydrogen is in the chain of carbon that make the organic matter, in the phenolic chain, and also the hydrogen when add in the oil you get a kind of fat the hydrogenated fat that if wasn’t to get add hydrogen to his chain would be liquid the hydrogen make it solid , also the hydrogen is the smallest atom and is a noble gas, and his number in the atomic table is one it is the first of the table, so probably even in the space that is the vacuum or the inexistency of matter have also a lot of hydrogen that is in the air and in the water that the life need so much at least the one in the Earth and is in the chain of the organic matter of carbon that is the structure of the life, if the life of other planets isn’t based in the same chemistry of Earth probably our air and environment would kill any alien, and had life that don’t need air? Yes, in Earth had the bacterium that is anaerobic, like the ones of putrefaction and also there are microscopic life in the deep of the ocean on the abyssal depths that synthetize and they don’t had the solar ray but is near oceans under water Vulcan, and they synthetizes with sulphur, I learn this in school. And also for who don’t know what is a cosmic ray, is a ray that you can’t related with a star or any other source, so if I don’t know the source of the ray it’s a cosmic ray, could imagine that had rays that is combination many lights of many sources, or generated without a star and also rays that is travelling for centuries, could a ray be older that its resource that blow many years before, like the first ray of a star that explode and the ray still today is travelling. And one definition for sun beyond be a star, don’t matter the size the sun feed a system so could be more than one so is the light for its spatial bodies so in a system the sun is the star that emanate the rays that provide illumination for the bodies of the system, sun means importance.
