In biology, evolution is the process by which populations of organisms acquire and pass on novel traits from generation to generation. Its occurrence over large stretches of time explains the origin of new species and ultimately the vast diversity of the biological world. Contemporary species are related to each other through common descent, products of evolution and speciation over billions of years.
The basic timeline is a 4600 million year old Earth, with approximately:
4000 million years of simple cells (also known as single-celled organisms),
3000 million years of photosynthesis,
2000 million years of complex cells,
1000 million years of multicellular life,
600 million years of simple animals,
570 million years of arthropods
550 million years of complex animals
500 million years of fish and proto-amphibians,
475 million years of land plants,
400 million years of insects and seeds,
360 million years of amphibians,
300 million years of reptiles,

Go Patrick and Matt A, you get the golden star for being both in denial, AND ignorant.
The Mt St Helens issue is an old and easily countered christian position, as are the dinosaur and human footprints in the same strata, etc..
Dating techniques are many and varied, yet ALL tell the same story, so even IF they were flawed, why do they all concurr..?
What evidence do 'I" have?
This is not MY evidence, however there is overwhelming scientififc evidence, and it is freely accessable to any who would like to see it, or challenge it..
You'll have to do much better than that..!

Easy Writer, my source is modern mainstream scientific concepts and principles, and I stand by it..!
Another clue for you should be that all the many and independant fields of science also concurr, and make an interweaving, self checking overview of the natural world..
How can this be so easily ignored by you and your ilk..??
