That is not my position. There is room for discussion. Early on I asked for anyone to provide me with a better explanation to account for common pseudogenes in primates. Specifically humans and chimpanzees. It fits perfectly well and indeed would be expected in an evolutionary model that includes common ancestry. Pseudogenes are the markers we use all the time to determine paternity and consanguine relationships. We use them in our legal system to convict or exonerate criminals. But when the same pseudogenes also show not only humanity's relationship with other animals but matches temporal distance of kinship expected by evolution in most cases, suddenly there must be some unnamed problem with using them as evidence. I feel that if someone denies genetic evidence for evolution then it is only honestly consistent that they adamantly oppose the use of DNA in our legal system for paternity or criminal conviction since it is based on the same understanding and same types of markers.
You see, these are not just statements. The evidence is tangible in the cells of every living thing. I believe you have a responsibility put forth an effort to understand what evidence leads scientists to accept a particular conclusion. Scientists are not accepting a statement. They are observing and interpreting and then justifying the interpretation with logical inference, deductions, experimentation, etc... It is wholly different than the baptismal example you gave. An example I am familiar with since I grew up in a complete immersion church.
The most obvious way the two are different is in the results. There is no general consensus opinion on baptism in christianity. It is given different weight and different meaning by a variety of churches. I would not expect christianity to ever reach a general consensus about baptism among all the churches throughout the world. But scientists have reached a general consensus about common ancestry throughout the world. How? They're people too, just like christians- with their own opinions, doubts, and beliefs. But it works because science relies on logic and observation of the world, not on authoritative sources like leaders or scripture. People can have differing opinions. But logic generates consensus. It's the same reason we don't have differing opinions on what 2 + 2 equals.
Sure, you might throw out tons of "documentation" backing up your beliefs, but the fact remains, that I am unwilling to take a scientist's word for it until he can show me how whales become dogs or monkeys become humans. Simply saying that it happens is not sufficient for me.
Scientists have shown "how" those things could happen. As I said, I believe you must take some responsibility to educate yourself on how scientists say these things could happen if you find it doubtful. Do you accept when scientists tell you the Earth goes around the sun? Do you accept when science tells that we are made of atoms? Do you accept when science tells you that germs cause disease? It is inconsistent to only accept scientists at their word when one chooses to. It is the same sort of mentality that lets people pick and choose out of religion the parts they want to accept and just conveniently deny the uncomfortable parts.
