Ok, two questions here, so I'm first gonna answer the one from Marwin/partydevil and then the one from Ramses.
Right after the Big Bang, the whole (small) universe only consisted of pure energy. It expanded rapidly and thereby created (or better: defined) space. However, the density of radiation was so high that the existance of atoms was impossible. Moreover, matter and anti-matter were created alike. Both destroyed each other, transforming themselves into energy again. It is one of the big questions of today, why a small portion of matter remained in the end.
However, about 10 seconds after the Big Bang, protons and neutrons connected to form the first Hydrogen, Deuterium, Helium and Lithium cores. The abundances roughly were 75% Hydrogen, 25% Helium, 0.001% Deuterium and very little Lithium. This was the so called phase of primordial nucleosynthesis. The remaining neutrons dissolved into protons and electrons during the following 5 minutes.
So the Big Bang created no other elements than these simplest ones: Hydrogen cores just have 1 proton. Deuterium is "heavy Hydrogen", i.e. Hydrogen with an additional neutron. Helium got 2 protons and 2 neutrons and Lithium consists of 3 protons and 4 neutrons.
All "higher" elements were produced by stars later on. For example, the fusion processes in the core of our Sun create Helium from Hydrogen. More massive stars can fuse Helium atoms and thus create Beryllium and Carbon. Even more massive stars can fuse Carbon, and so on. The "highest" element stars can produce by fusion of Silicon is Iron (atomic number 26). The fusion reactions beyond that barrier are exothermal and the required temperatures would exceed 30 billion degrees Celsius by far.
Elements with even higher atomic numbers (like Copper, Silver, Gold, Lead and all the others) are produced by supernovae of type II only. These supernovae are explosions of stars with a mass of 8 solar masses and above. Such an explosion releases unbelievably high energies (in the range of 10 to the power of 51 erg). The energy compresses the atoms and thus leads to fusion of the "higher" elements. At the same time, all elements created by the star are scattered through the surrounding space.
Stars form from cold molecular clouds. These days, such clouds almost always are remnants of stars that exploded millions or even billions of years ago. Observed stars are divided into so called populations. Population III stars were the first stars that have formed and these naturally consist of no higher elements. Population II stars formed billions of years after these and contain the higher elements created by the population III stars. The youngest stars (like our Sun, which is an intermediate population I star) have a high abundance of these higher elements. Scientists generally call the abundance of elements other than Hydrogen and Helium metallicity.
Now since the Sun and its planets have formed from the remnants of older stars and no other elements than mainly Hydrogen and Helium were created during the Big Bang, this means that all atoms in your bodies (except these two) were created by fusion in the core of a no longer existing star or in a supernova explosion. Thrilling thought, isn't it?
Now about Ramses' question:
Light naturally travels with the speed of light (which approximately is 300000 kilometers per second). So whenever we observe something in space, we have to consider that the light emitted by the observed object has to travel the distance to Earth. Even if light is extremely fast (in fact,
nothing is faster at all), it can't travel faster than that. For example, the Moon has an avaerage distance of 384000 km. This means that the image of the Moon that we see in the sky is somewhat older than 1 second when we see it. The distance of the Sun is about 150 million km, so the light of the Sun that we see on Earth has travelled 8 1/2 minutes before it reaches our eyes. If for some reason the Sun would explode now, we wouldn't know anything about it in the following 8 minutes.
For higher distances, the delay increases more and more. For example, the star closest to our Sun is Alpha Centauri and is 4.22 light years distant. A light year is the distance that light can travel within a year (i.e. the amount of seconds in a year, multiplied by 300000). It equals a distance of 9.46 quadrillion kilometers. So the distance to Alpha Centauri is approximately 40 quadrillion kilometers. Light travels that distance within 4.22 years, which is why the image of Alpha Centauri that we see on Earth is more than 4 years old. That means that the state of Alpha Centauri we currently observe is from a time when I wasn't a member of this clan.
When we look around ourselves in space, we find that everything we see disappears from us. Basically, we can assume ourselves to be somewhere between the center of the initial Big Bang and the border of the universe. The universe still expands and the outer border moves away from the center with approximately the speed of light. The space inbetween is being stretched at the same time. Imagine you have a balloon with no air in it yet. If you draw small black dots on the surface, you can see each dot disappear from each other when filling it with air. It's the same in our universe, just in three dimensions.
The expansion of the univserse was discovered by Edwin Hubble in 1929. The determination of the expansion rate (called Hubble constant) is a subject of ongoing investigation until today. Recent observations claim a value of about 69.7 kilometers per second per megaparsec. This means that an object with a distance of one megaparsec (equals 3.26 lightyears) disappears with a speed of 69.7 km per second. Farther objects disappear even faster. It's just like with the dots on the ballon: The distance between more distant pairs grows faster than between nearer pairs.
Due to the fact that space itself is being stretched, this also means that the waves of light are being stretched. Therefore, light from distant places is more stretched than that of nearer places when it reaches Earth. Since light with longer wavelengths is nearer to red than that of shorter wavelengths, astronomers say light is being red shifted. Thus the amount of the shift in fact is an indicator for the distance of the observed object.
Anyway, to answer Ramses' question: Since no object disappears faster than the speed of light, we're able to see the light of even the farthest objects. In fact, the most distant object observed till today has a redshift value of 8.2, which means that its light was emitted only 600 million years after the Big Bang. Or in other terms: Since the universe is said to have a radius of 13.7 billion light years, that object would be 13.1 billion light years distant.
. Surely we can't be accelerating away so fast ... but I'd have to get a calculator and convert to miles with light speed and those megaparsecs etc to work it all out
