Listen...
I believe Sidious did create Anakin, a perfect apprentice with such high abilities. It was asked by mephistodesigns exactly why Tatooine would be the planet for Anakin to be born upon instead of a core planet... Here's why. If Anakin were born upon a core planet, the Jedi would've recognized him and have taken him in early!!! That's exactly what Qui Gon said in TPM.
I believe Sidious wanted Anakin to grow up and have attachments but later become a Jedi at an age much to old to begin the training. His training would at least put his "foot in the water" when it comes to using the Force. The early attachments of Anakin's would serve as his undoing and his lack of Jedi ideals. The seed of attachment was already within Anakin, all Sidious had to do was play upon that and Anakin could become his apprentice.
Someone asked why Sidious would zap his own grand kid... HELLO!!! This is Darth Sidious we're talking about here. The Dark Lord of the Sith! He killed his own master as many Sith do. Get a grip.
Besides, I think Lucas adding in lines about the ability to create life though the Force, and Anakin having no father is pretty obvious of what he wanted to imply.
