However Science, by its very nature on depending on empirical observation and experimenting can adjust quicker to new ideas of thought and discoveries than religion. I find that the big three, Judaism, Christianity, and Islam, as dinosaurs in spiritual beliefs and if they do adapt to modern thinking and join the 21st century they will lose their intrinsic nature of being what they tend to teach because the very heart of their scriptures are centuries upon centuries old with very little flexibility and adaptability built in to them. For a prime example is the acceptance of homosexuality and gay marriage. Even some of the more liberal minded Christians would balk at the allowance of gay marriage let alone more conservative factions, however homosexuality is a part of our society and with human sexuality being a phsyiological drive they do not see that a person cannot 100% control who he or she is attracted to. Its that type backward thinking that hampers progress. They same can be said about stem cell research. There is no scientific evidence of a soul. There is no scientific evidence that an embryo is any more self aware than a skin cell or gnat. It is a collection of cells and nothing more, yet we have Christian groups claiming, without any sort of evidence to back this up, that an human embryo has a soul and should be treated the same as any living person. If it wasn't for Christianity and Islam ruining civilization with their constant fighting, both with each other and within, and hampering progress of civilization we just might be a slightly more advanced people than we are now.
