What is evidence?

[Arkilogue]

That there is any specific direction to the evolution of life, and that if there were, it would be complex organisms.  Beyond any questions of how slippery your metrics are for complexity, or in what sense you may be deigning to use the term....it's simply an untenable position.  We know it to be untrue.  

If some method that you've applied to some observation leads to known, and demonstrably false, conclusions...then their is either a problem with the method..or the observations.  Your observation, apparently, had to do with the presence (or lack thereof) of spikes in a tree.. seems to be fairly mundane...but this extrapolation from that is so fanciful that I'm surprised that I even have to elaborate, and leaves me entirely certain that the problem is in method.

More complexity meaning greater ability through either body or senses to gain information and interact with/take advantage of the surrounding environment. Barring severe interruption of environmental constants.

The two are unrelated, I said so before starting this.

But if you want something related, I suppose the absence of spike holes in most people lives could be evidence that God does not constantly prune us, and is largely absent from interfering with the trees growth beside environmental factors. If life is like a season of growth and fruiting, death is like the season of harvest and pruning.

Weirdly enough I have found a dead God in the crown of the world tree....several of them infact....long dead.

Also not related to the absence of spike holes, just my lateral thinking mind going side-ways.
