Then! Cientificamente you cannot deny true the historical one of this philosophy: Beyond the Universe the life also is infinite in the Land, and all the species also the man have certainly ancestral origin, where the pursuing of the life (for the future) results in an arrival to the past of Daily pay-History; e that finishes in return to the gift of Our Historia.

I circulate that our alternating History of Daily pay-History is happened again infinitely.

I believe it's only a matter of time before scientists learn how to read the mind they way a computer reads data. It's really just a matter of figuring out the interface and how to decode the signals. In fact, I think it's very likely a day will come when scientists could literally upload and download information to the brain. Obviously this would create an unknown variety of possibilities - some very scary while others are more exciting.

Do you fear the day when this becomes reality?

questions and evidence , cause we all know there is only one true relgion and one tru concept, while we humanbeing have many different relgions ! , so for every one to first ask GOD, to show him the truth , who is He , where is He ? what is the truth , ,, is He one , or two or three ,or what !!! it is serious before u die and then !!!!!!!! {hell for ever ,or heaven}
so we must be sure < if i say my reliigion is the truth , so what is the evidence, ,, be carefull don't only follow ur mum and dad concepts without thinking ! we only have one chance and this is our chance , so search and search hardly for all evidences and ask people who know well about his religion ,
don't ask a man about a religion which he do not follow . because sure he will say bad words about it to just make u follow his religion ,
don't ask jewish about christanty
don't ask christan about islam
don't ask christian about jewish , and so on
search for truth in every where nature, science,
