You shouldn't be mentioning science considering that it you who completely ignores the science and base your assertions on subjective experience.
Nobody disputes the fact that we can move our fingers at will, or engage in hand waving like you....but this ignores the mechanisms by which we first feel the impulse to move and the motor action of movement.
The latter is what you studiously ignore, just to repeat the former, which nobody is disputing.
Here's a primer...not that it'll help you understand. You don't want to learn.
Abstract
''Are we in command of our motor acts?The popular belief holds that our conscious decisions are the direct causes of our actions. However, overwhelming evidence from neurosciences demonstrates that our actions are instead largely driven by brain processes that unfold outside of our consciousness''
Introduction
''In daily life, we usually have the feeling that we are the authors of the actions we make, that the decisions we make and the corresponding movements we perform are consciously initiated and controlled. The belief that our actions are caused by our mental states, and these mental states are causally independent from brain processes reflects a dualistic philosophy (Descartes, 1641). However, the current scientific view holds that human actions and mental states are both biologically determined and stem from patterns of neural activity in the brain.''
Voluntary action is unconsciously generated
''The idea that intention is a direct translation of desires and goals into behavior is deeply embedded in our culture. But it is supported by experimental evidence? That is the question which interested Benjamin Libet 30 years ago (Libet et al., 1983). In his pioneer experiment, participants were asked to make a voluntary movement at will and to report the exact time on a clock at the instant they had decided to move, while their readiness potential, a change in electroencephalography (EEG) activity over the motor cortex that occurs prior to voluntary movement, was being recorded. The results showed that the preparatory motor activity began more than 350 ms before subjects became aware of the decision to act. More recently, Soon et al. (2008) used a brain decoding statistical method to show that an action could be predicted by blood-oxygen-level-dependent functional magnetic resonance imaging (BOLD fMRI) signal. Although the volunteers felt they consciously decided to move, the vector machine could classify the outcome of their decision by means of the activity in several cortical regions, such as the precuneus and the fronto-polar cortex, up to a few seconds before the decision to move entered awareness, while the activity in the supplementary motor area (SMA) determined the timing of that decision.''
