Jor-el you are showing a very poor understanding of the word theory in scientific terms there. I'd like to see the evidence for 250000 or 500000 of Homo sapiens though (btw never capitalise the species name, only the genus name).
The evidence for 500,000 years ago is indirect and unsettled, but relies on the fossil discussed in the following article (I think.)
QUOTE
Fossils from the Gran Dolina railway cut in northern Spain's Sierra Atapuerca are from a hitherto unknown species of early human, according to the site's excavator José Bermúdez de Castro of the National Museum of Natural Sciences, Madrid, and his colleagues. They named the newly identified species Homo antecessor (from the Latin for pioneer or explorer), and claim that it is directly ancestral to both modern humans and Neandertals.
The Gran Dolina fossils--nearly 80 postcranial, cranial, facial, and mandibular bones as well as teeth of at least six individuals--were excavated between 1994 and 1996 (see "The Peopling of Eurasia," ARCHAEOLOGY, January/February 1996). A key specimen is a partial facial skeleton of a juvenile, estimated to be ten to 11 years old, recovered in 1995. The fossils exhibit both seemingly modern features, such as sunken cheekbones with a horizontal rather than vertical ridge where upper teeth attach and a projecting nose and midface, and more primitive ones, including prominent brow ridges and premolars with multiple roots. The level in which the fossils were found, TD6, is dated by a reversal in the earth's magnetic field to more than 780,000 years ago. So far this level has been exposed only in a test pit of six square meters, but the excavators are confident that many more human fossils will be found when the larger excavations reach the level some years in the future.

According to the now available archaeological data, Homo sapiens sapiens, as a species, might emerge in circa 200 million years ago in Africa, and gradually appeared in the Middle East, Asia and Europe during the modern age.

Scientists from the University of California at Berkeley along with researchers from Ethiopia and several other countries have uncovered fossils of the earliest modern human, Homo sapiens, estimated at 154,000 to 160,000 years old. According to the scientists, the findings provide strong evidence that Homo sapiens and Neanderthals co-existed, rather than the former descending from the latter.

The replacement model of Christopher Stringer and Peter Andrews proposes that modern humans evolved from archaic Homo sapiens 200,000-150,000 years ago only in Africa and then some of them migrated into the rest of the Old World replacing all of the Neandertals and other late archaic Homo sapiens beginning around 100,000 years ago. If this interpretation of the fossil record is correct, all people today share a relatively modern African ancestry. All other lines of humans that had descended from Homo erectus presumably became extinct. From this view, the regional anatomical differences that we see among humans today are recent developments--evolving mostly in the last 40,000 years. This hypothesis is also referred to as the "out of Africa", "Noah's ark" and "African replacement" model.

The oldest "modern" human remains outside Africa, from Qafzeh in the Middle East may be as old as 100,000 years and those from Mount Carmel in Israel, 80,000 years old, but humans only flourished at the time of the extinction of the Neanderthals around 35,000 years ago (Reader, 1988) (Roe, 1990) (middle and early upper Pleistocene). Within Africa the oldest modern humans are just less than 160,000 years old and represented by Homo sapiens idaltu. Another Homo sapiens skull from Dali, China, is dated at 200,000 years old. It has a cranial capacity of 1,120 cc. (Johanson & Edgar, 1996). In Africa, 21 sites spanning Africa from north to south (Libya, Morocco, Algeria, Sudan, Ethiopia, Kenya, and Tanzania) and dating from 500,000 years to 30,000 years ago have yielded fossils with predominantly modern anatomical characteristics.
