Before you answer this question, remember that in science a theory is the final point of the scientific method. After hypothesising, evaluating and testing the circumstances a theory is developed which means that this is the truth as we know it. The theory of relativity has never been in question, why is Evolution so hard to swallow?

How do you explain ancient fossils, bones and rocks?

How do you explain bacteria that become resistant to drugs?

If you choose to answer this question with an explanation that evolution is not true beware: There is overwhelming evidence for it and the lack of evolution in religious texts is meerly because they were written within the last 4000 years (only an eyeblink in the life of the universe).

Back to the question, is it because they are not being taught how to learn for themselves? Are they not being given enough diversity in religious education? Is the level of science teaching poor?

If I have a grouped frequency distribution is it ok to use the standard deviation or should I stick to median and interquartile range for summary statistics? I'm not sure if the intervals mean that I have lost too much information for the sd to work.

And what exactly does a speedometer tell you? I would have thought it's only possible to know your speed over a certain time and distance, not in any single instance?

Furthermore how can it tell you how fast you are actually travelling as opposed to simply how fast your wheels are turning?

I've heard that the body loses 21 grams as soon as somone dies, and that this represents the weight of the soul.

Two questions: what's the source of this, and is there any truth in it? And does your soul weigh more if you're heavier in real life?
