      Due to the gigantic size of the universe, statistically there is more life out there somewhere. On another planet somewhere in the universe, conditions may be favourable enough for another type of life to exist. However it is probably very different to the world we know.

      These ‘aliens’ probably have some sort of ‘genes’ or units of inheritance but they may not be DNA as we know it. Their genes may be made of completely different molecules. All that is required is that these molecules can contain some sort of code that can be passed on to offspring.

      This is an area where the imagination can run wild!

      Well I don’t know if there is anything beyond the universe!

      Our galaxy on the other hand is made up of between 200million and 400million stars, many of which are like our sun and with rocky planets in orbit. There are 125billion other galaxies in the universe too, so the likelihood of life elsewhere (even whole other worlds) could be great, or if life is extremely, statistically unlikely to occur, then it might not be at all likely that there are other worlds!

      Of course, someone, somewhere could be having this same conversation.
