According to an NBC News report some years ago, there was a “remarkable” discovery in Australia. They said the Journal of Science reported that they had found what they considered to be proof that life appeared on earth 2.7 billion years ago—a billion years earlier than previously thought. They now admit that they were wrong in their first estimate (a mere 1,000,000,000 years off), but with this discovery they are now sure that they have the truth...until their next discovery.
The CBS News reported that discoveries were made of the bones of an unknown animal in Asia that may be as much as 40 million years old. This changed scientific minds as to where man first originated. Scientists once believed that primates evolved in Africa, but now they think they may be wrong, and that man’s ancestors may have originated in Asia. So they believe . . . until the next discovery.
