Could this not be due to something being wrong with the scientific methodology?
While, of course, anything is possible, the likelihood of this being the case is very small indeed. At this point in time, with all the knowledge we have, there is no way "Adam" and "Eve" lived at the same time. Of course when there is new data, this can always change, but until then, we should assume that this is correct, regardless of what we would like to believe about such things.
Please, don't be too aggressive. I am just trying to make a sound argument here.
Of course. If you read the link I posted, you will see there explained that ME wasn't the only woman alive at the time, she is just the only woman with an unbroken female line until the present day. Just like "Adam" is the only man with an unbroken male line until the present.
Yes. But even "all the knowledge we have" today about ME and YcAdam cannot be considered sound knowledge. Isn't the knowldge we have about ME and YcA pretty primitive?
We know absolutely nothing about "Adam" and "Eve". What we do know about are genetics. And everything we know about genetics says they did not live at the same time. If you have data that questions this finding, please present it. Until that time, there is no reason at all to question the outcome. Your preferred belief that they lived at the same time does not replace the data we do have that says they didn't.
