I am glad you mentioned the last sentence which I agree with...I would phrase it or say somthing relates to it which is 'we may never be sure on something'...

the answer might be arrived at by means different to how we usually do things..The means may be things such as knowing the answer by elimination, or calculating the probabilities or otherwise.

I think we have a problem in managing our debate too..which leads to losing each other..which I will try to overcome...

I need to read about evolution and come back once done with more arguments and suggestions..

In the mean time, please keep thinking about previous posts- which I do. We may make progress by intelligently questioning our observations.

Will be back!
