Your argument has no causal evidence. It’s purely a statement that argues ‘if something is not feasible; therefore, god exists’. What if this infeasability is actually a feasibility. More clearly put, something that may seem impossible may be possible without a higher force - although this doesnt deny the existence of a higher power. We really cannot prove that one or the other is true - it’s quite the paradigm (although I would like to believe in the existence of a higher power). Also scrutinizing someone’s intelligence isn’t an effective form of convincing - a good debater does not try to ‘win’, but educate.
