It didn't say that oxygen creates life. Think when you read.
Thanks. My bad. It says oxygen creates fossils.
Seriously, this is what the article says:
" ... the first appearance of oxygenated conditions in the world’s oceans and the first appearance of large animal fossils confirms the importance of oxygen as a trigger for the early evolution of animals, the researchers say. They hypothesize that melting glaciers increased the amount of nutrients in the ocean and led to a proliferation of single-celled organisms that liberated oxygen through photosynthesis. This began an evolutionary radiation that led to complex communities of filter-feeding animals, then mobile bilateral animals, and ultimately to the Cambrian "explosion" of skeletal animals 542 million years ago.
I'm sorry, I simply don't believe a change in the mix of chemicals in the oceans or atmosphere will "trigger" evolution of animals from single-celled organisms.
Even Darwin believed it was a mutation within an existing species which triggered evolution of a new variant. If the mutation was better for survival, the mutated creature lived on, and passed on the mutation.
As an example, consider the following: Did giraffes grow long necks because the trees were tall (environmental trigger), or did mutated giraffes with long necks (genetic trigger) survive and pass on their genes because they could eat more?
This is one of my complaints about those who believe evolution explains the creation of life forms (it does not), rather than just the adaption and change of life forms.
Many evolutionists find it absurd someone can believe the following:
"And the LORD God formed man of the dust of the ground, and breathed into his nostrils the breath of life; and man became a living soul."
but believe inanimate matter can become a life form. And apparently can believe an increase in oxygen can cause oxygen breathing creatures to evolve from photosynthesizing creatures.
I would put forth the notion that both of these beliefs are based in faith in certain fundamental assumptions.
There is never going to be any evidence proving dirt became life. It is a matter of faith for atheist scientists as well as religious people.
