Biggest extinction in history caused by climate-changing meteor
phys.org ^ | 8-1-2013

It's well known that the dinosaurs were wiped out 66 million years ago when a meteor hit what is now southern Mexico but evidence is accumulating that the biggest extinction of all, 252.3m years ago, at the end of the Permian period, was also triggered by an impact that changed the climate.

While the idea that an impact caused the Permian extinction has been around for a while, what's been missing is a suitable crater to confirm it. Associate Professor Eric Tohver of the University of Western Australia's School of Earth and Environment believes he has found the impact crater which reveals though the trigger was the same, the details are significantly different.

Last year Dr Tohver redated an impact structure that straddles the border of the states of Mato Grosso and Goiás in Brazil, called the Araguainha crater, to 254.7m years, with a margin of error of plus or minus 2.5m years. Previous estimates had suggested Araguainha was 10m years younger, but Dr Tohver has put it within geological distance of the extinction date....

fwdude, you appear to be one of those who consider acceptance of science to be rejection of God. And there are those who would try to use science to disprove God. But without God, all of those wonders had to spring from nothing.

He will explain it all to us, I’m sure.

Even Peter said that to God a day is a thousand years and a thousand years is like a day.(2Peter 3 8).

And, given the level of education in those days, a thousand was understandable, but millions or billions were not a concept easily grasped. The scriptures were written to be understood.

There is no science involved in blindly accepting evolution and deep time. You’ve been had.

could you provide a specific list of scientific beliefs it takes to be conservative? And those which are held by liberals. You can skip evolution and just give me the rest.

Thanx.
