The idea that the world was created in 7 days and a biblical flood and the tower of babel was assumed as fact by me as soon as I read about such things in the bible. I was 6 years old at the time. Every sermon I listened to from then on confirmed that belief. Every family member of mine believed it except my stepfather who was catholic. It wasn't until 8th grade biology that I heard anything different. It wasn't until I was an adult until I started hearing serious discussions about evolution.
Some of these issues science can readily test.
As just one example, the global flood ca. 4,350 years ago was tested initially by creationist geologists seeking to document that flood. They could not do so, and had to admit that the flood did not occur as described. This capitulation occurred in the early 1800s, long before Darwin.
Since then the evidence that there was no global flood ca. 4,350 years ago has become overwheming. It is so easy to disprove this that any archaeologist can do it.
I've done it in my own research. What one needs to do is find an archaeological site that cross-cuts the 4,350 year time period. A site that does so by thousands of years is best. Then you examine what occurred before and after that time period, and you look to see if there is any evidence of a major discontinuity at that time.
What I have found in the many sites that I have tested is that there is no discontinuity about 4,350 years ago. Instead there is
continuity. I've seen continuity of human cultures, fauna and flora, sedimentary deposition, and mtDNA patterns. This last one is the most telling: the mtDNA patterns were the same both before and after the 4,350 year date.
This shows that there was no discontinuity, as would be caused by a global flood which wiped out all but a select group in the Near East. If there was such a flood, all human mtDNA would be eliminated at about 4,350 years ago and would have been replaced by one type from the Near East (Noah's female kin). This can be shown not to have happened. The same type of evidence can be shown for all fauna and flora: there was no extinction-repopulation event in recent times.
This is the kind of evidence that scientists look at.
Religious belief does not constitute scientific evidence, nor does it convey scientific knowledge.
