and who is accepting or learning from an failure ? since you have been failed in telling us the name of your 10th grandfathers, 10th grandfathers, grandfather. but you are jumping beyond him. ( just see the fun ) so i dont accept anything from an failure like you. and you are talking about scientific facts ? ( just see the fun again ) what do you know about scintific facts ? real science is not an childs play that you accept something now and reject the next momment. ( it is not like your modern nonsense imaginations ) it will remain as it is was before for eternally. and believe it or not but fact is fact.
