You got something that one might call real evidence? I don't happen to agree that showing some connection between a book and the real world is evidence of a god of any kind. If you want to go that way then you must show some evidence that the book you are pulling the connections from is not just a work of fiction.
yes i do but you just choose to ignore it don't you

I am not trying to convince you that the big grumpy sky fairy doesn't exist, I don't give a tuppenny damn whether or not you choose to believe in mythical nonsense. You, however, wish to convince me of the existence of your god. So go to it, convince me.

I realy don't want to convince you anymore, so PREPARE YOURSELF FOR HELLFIRE!

But I think we can agree that a banana tree is alive.
I have actually seen bananas with seeds. I don't know if they were fertile.
However, asexual reproduction by cuttings is still reproduction, and bananas can evolve albeit slower than sexually reproducing organisms.

Cuttings require human intervention ... but I guess you could call that
symbiosis!
Is there evolution through cuttings? I thought that all bananas of one
species were essentially clones.

It doesn't matter what it requires, it is reproduction nonetheless. Vegetative reproduction is commonplace in plants and only in particular domesticated species does it require human intervention. Bananas reproduce perfectly well without human intervention, it is only long distance transport that requires humans. Bananas evolved this method of reproduction prior to human domestication. They also reproduced via sexual mechanisms - hence the fruit.
Is there evolution through cuttings? I thought that all bananas of one species were essentially clones. Yes there is evolution. Clones are never perfect copies. Even the cells in your body are not perfect copies of one another. As I said, evolution is slower as there is reduced mixing of gene-pools, which is why sexual evolution is so successful. I must note though that plants are quite good at swapping genes via virus' etc and this is often inter-species.
Note that there are a number of varieties of bananas. Where did you think they came from? Actually many banana varieties can reproduce sexually, but I am sure that some varieties arose through vegetative reproduction.

The world's sexiest fruit is a sterile, seedless mutant - and therein lies a problem. The banana is genetically old and decrepit. It has been at an evolutionary standstill ever since it was first propagated in the jungles of South-East Asia at the end of the last ice age

and ... because developing new varieties without the help of sexual reproduction is expensive and time-consuming.

A bit of a contradiction there. If it is at an evolutionary stand still no new varieties can possibly arise. If you read the Wikipedia page you will find there are not only several species, varieties withing species and also hybrids. I can recall eating at least three different varieties.

I think they are referring to macroevolution, a.k.a. evil-lution.
