The Universe is believed to be about 14 billion years old, whilst our Solar system is only about 4.5 billion years old. Our Solar system is sometimes called a '3rd generation system' as it results from several episodes of stellar accretion and destruction, each one generating more sophisticated elements. [But our Sun, being small, can only generate elements up to iron, because the Sun's size and temperature allow no further nucleosynthesis, (as it is called).]
