The probabilities of life forming by chance and then evolving are so small that they become impossible even with the allotted billions of years of time.
Oh yeah? Exactly what are the probabilities? Numbers, please, and I'd like to see your math.
How small a probability is "impossible"?
They are refuted by the cambrian explosion
The "explosion" you refer to constitutes a time period several million years long. To put that into perspective, a lot of the plant species you're familiar with day-to-day are significantly younger than that.
lack of intermediary fossils
No such lack.
Transitional Vertebrate Fossils FAQ. As you can see, among the species we would expect to fossilize - vertebrates - we find a number of transitional forms.
(such as the human footprints at Glenrose).
This is just a flat-out lie. There's no such footprints.
I once believed in evolution because thats what I was taught in school.
Well, no wonder you're a creationist - you believe things for the wrong reasons.
Around here, you'll find that evolutionists are convinced by evidence, not by authority or pedanticism. Care to provide some evidence?
This is statistically impossible
There's that argument from statistics, again, but you keep forgetting to
actually give any statistics. Why is that, exactly?
however I still would like for someone to go to Glenrose and place their feet in the footprints and come back believing they aren't human footprints.
I've seen pictures of the "footprints" you're talking about - the 20" long ones, right? - and I don't see how anybody but an idiot can come to the conclusion that an enormous, misshapen, eroded pit with no visible toeprints, heel depression, or instep is supposed to be a "human footprint."
Unless you're talking about different prints, or something. It'd be nice if you could hit us with pictures.
