Stop being so misanthropic! It could give humanity a chance to terraform otherwise dead planets on a massive scale, allowing us to spread life throughout a mostly nonliving universe.
One of the tenants of Christianity (at least for most modern Protestant and Catholic sects at least) is that you're supposed to accept Jesus as the messiah. In fact, you could say that Jesus being the messiah is the most fundamental aspect of Christianity which distinguishes from Islam and Judaism.
"Race" remains completely historically and culturally subjective. Jesus had no "race" in modern terms because he lived in ancient times before "Black," "White," "Asian," "Latino," etc. had been invented for socio-political purposes.
Do you mean Hinduism as we see it today? Because Vedic Hinduism is a lot different than Modern Hinduism. . . I think we should probably take this discussion to another forum.
Hinduism may be historically syncretic (ie, the traditions of the Aryans and the Dravidians mixing) but it is typically seen as an indigenous religion. Because of this, Indian traditions and Hindu traditions are often only separated by the personal prejudices of the historian/theologian/etc...
