Buddhist Ontology/Reductionism vs Science

Dear Mighty friends and learned colleagues, I am a Scientist and have been a philosopher (I don't want to reveal my identity) so far. I have been a strong theist, raised up in an orthodox Hindu Background, with vedic training. So I read Vedas and other texts and always believed in God. Sometimes by convention and sometimes by experiential intuition. God was - unfortunately or fortunately - presented to me in a dogmatic manner. Top-Down. Here is God. Take it. Accept it. Believe it. I was OK with it, till it started to disturb me deep down. Firstly due to my heavy involvement with the foundations of sciences, I was caught in the method of science. So I can't believe in God and do my science at the same time. At one point one has to give up traveling in two boats. Buddhism offered solace at that point. I thought it's a logical religion. Totally banishing the dogmas and blind beliefs. But I found some paradoxes in it as well. Perhaps due to my ignorance. I will be grateful if someone throw some light and enlighten me here: **Buddhism's ontology posits a world which don't need a creator. That's fine. But how about the soul? What proof does Buddha have for soul? and What about reincarnation? What are the proofs for it?** What about the Maitri? or Metta? When you close your eyes and let your heart radiate, should we imagine a field (akin to quantum fields) that radiates outside your heart? What's the proof for this again? Also what about Karma? How can I reap bad when I sow bad? Where does this transaction take place? In ordinary space-time? Because attributing causality to action and reaction posited by Karma principle, is against the modern science whose fundamental elements are quantum particles. Where are this Good and Bad situated? What about Amitabha? So the issue is simple. In for pound. In for penny. If Buddhism doesn't accept anything by blind belief, then these elements should be dropped. Because there's no scientific/cognitive proofs of the aforementioned elements given our sensorimotor apparatus. Can someone enlighten me? Or suggest me some books? Any brief answers addressing these things will be greatly helpful. Your humble servant.
