how did we get so far away? sinple our sun is classed a second generation star. ie not one of our galaxies first. in our winter nights sky we have the constallation Orion, and within this constallation we have Orions belt and Orions sword. this is (orions sword that is) a glowing expanse of gas and dust termed a nebula. within this nebula stars are forming, and indeed the nebula shines because of four large newley formed stars within. these are stars that have formed within the last 10's of millions of years NOT 14 billion years. so theses stars are being formed well past the big bang, our sun formed the same way, 4.5 billion years ago, so a gap of 10 billion years has passed between the big bang and our sun being formed, hence the distance of these remote galaxies we are now seeing.
i said our sun is a second generation star, this is because when the first stars formed there was only hydrogen helium and a few trace elements, the other elements such as carbon, oxygen, lithium, sodium and iron can ONLY be formed within a stars core, once the element iron is reached the star will stop its reactions and implode then explode. the implosion then will create the heavier elements such as gold, uranium, (all the elements that come after iron), as the star explodes the enriched gas of the explosion continues outwards interacting with the inter stellar medium or another gasious nebula enriching the nebula with new elements, and as that neblua contracts to form a new star that stars system will also be enriched. hence the saying "we are star stuff" every atom in our bodies came from the death of a first generation star.
