SCIENTIST: why won't you come up with this idea?

There indeed could be forms of life that do not follow the same "rules" as we do; in fact, such forms have been found near ocean-bottom vents. Whether or not they could become intelligent forms of life such as ourselves is another question. To understand the likelihood of this occurring, you should major in both biology and chemistry (especially organic chemistry) to learn about the interplay of biochemistry and energy as it pertains to living organisms.
