We could put forward the following counter arguments to the constancy of these assumptions: a) The constancy of cosmic ray bombardment might be questioned.
The current high rate of entry might be a consequence of a disturbed post-Flood environment that altered the .
Radiometric dating techniques are thus based on sound scientific principles, but rely on so many basic assumptions that Bible believers need not have their faith shattered by data derived from these techniques.
If dated with the carbon-14 method, the flow appears to be less than 17,000 years old, but dating with the potassium argon method gives dates of 160,000 to 43 million years.It's assumed that the clock was set to zero when the study material was formed.This requires that only the parent isotope be initially present or that the amount of daughter isotope present at the beginning is known so that it can be subtracted.Evolutionists assume that the rate of cosmic bombardment of the atmosphere has always remained constant and that the rate of decay has remained constant.Scientists place great faith in this dating method, and yet more than 50% of radiocarbon dates from geological and archaeological samples of northeastern North America have been deemed unacceptable after investigation.Local police collected samples of the curious rocks and handed them to the Medical Research Institute of the Sri Lankan Ministry of Health, who then passed them on to researchers at Cardiff University for further analysis, the study says.In total Jamie Wallis, of Cardiff's School of Mathematics, and colleagues received 628 fragments purportedly from the meteorite - three of which, they say, were 'clearly identified as possible meteorites'. Critics say that even if the rock was indeed from outer space, research into it has failed to prove that the traces of life apparently found are not the result of contamination here on Earth A previous study, led by Professor Wickramasinghe and published in the Journal of Cosmology in January, also claimed to have found 'microscopic fossilized diatoms (a basic form of algae)' in the samples.While there is no proof that the rates were different in the past than they are today, there is also no proof that they were the same.Thus radioactive dating relies purely on assumptions.The microorganism that fell to Earth: This picture shows a close up of the point marked (b) in the image above: The paper claims that the rock in which these were found came from a meteor which landed in Sri Lanka Mail Online first reported in January the claims by Professor Chandra Wickramasinghe, of the Buckingham Centre for Astrobiology, that investigations of the meteorite had revealed evidence of alien life.The paper tells how on the evening of December 29 last year a bright yellow fireball lit up the skies over Polonnaruwa, Sri Lanka, turning green as it disintegrated on entry into the Earth's atmosphere.
