Millions of years
Geologists and evolutionists are always giving us huge timeframes for the existence of things i.e. Grand Canyon is millions of years old, dinosaurs died out 65 million years ago. But there is evidence that these huge timeframes are simply wrong:
Canyon Lake Gorge, Texas, USA
This canyon formed in 2002 when Canyon Lake overflowed Canyon Dam[1]. The torrent of water cut a huge gash in the ground through what was just a nondescript valley. In just THREE DAYS, the rushing water gouged out a canyon 2.4km long and up to 24m deep. Most people are amazed to discover that such a huge gorge formed so quickly. Geologists now acknowledge that only short periods of time were needed to carve canyons such as this one. If we don’t need millions of years to explain geological formations we have observed forming, why do we need millions of years to explain geological formations we havn’t observed forming?
T Rex Fossil found with blood cells still inside
Red blood cells have been found in a T Rex fossil. This find casts doubt on the theory that all the dinosaurs died out 65 million years ago. [2]
