Bushbred,

We're certainly on the same side when it comes to our desire for all to live together in peace, while respecting our differences.

And yes, to the extent that science can serve as a kind of "universal language", recognizing the same laws and describing the same phenomena not only in different countries on Earth, but even in different locations throughout the Universe, it has the potential to serve as a basis for cross-cultural communication. But this has to be combined with recognition of some sort of basic universal morality. Science alone won't make people get along together.

Which, if you think about it, is sort of another way of saying "making the deserts bloom is not enough".
