Scientific knowledge cannot be denied. It can only be proved; or, as the case may be - disproved. However the case may be, scientific knowledge is always subject to improvement. The theologians, foolishly, denied that the earth rotates around the sun; denied that it is billions of years old; and denied that man evolved from other apes. Hell, the theologians even deny that science could cure diseases such as tuberculosis, measles, or even appendicitis. Poch Suzara
