They are scientists, and probably educated people, therefore they would seem to need evidence to be convinced of anything.
Thats a pretty huge assumption, for my own part I would assume most of that 40% probably believed in god before they became scientists, so they would already be convinced of his existence.
It is also possible when they encounter evidence to the contrary that it is discounted because they don't want to be seen as disregarding something that is accepted by the scientific community.
Thats a pretty huge leap there, you just magically poofed some contrary evidence out of nowhere. Do you have anything to suggest that such evidence actually exists?
So, are you saying that we should deny everything that ever happened in the history of the world if there are not eyewitnesses alive today to testify to the event?
No, I don't think you will find I did say that. Although it is worth noting that in many more recent historical events we still have original documents to draw on, what original eyewitness documents are there for the resurrection? The earliest written accounts are apparently from Paul's letters, and Paul surely wasn't an eyewitness, except of his own Damascene experience.
Their eyewitness testimony lives on today, just as the eyewitness testimony of the assasination of the American president Abraham Lincoln lives on today
We could find many examples of original newspapers reporting Lincoln's assassination the day after it occurred and original letters from the doctor who attended him. Do you really not see any difference in the standards of evidence available?
