You all got struck with the word MATHEMATICS! I can’t believe it. You are too innocent. I used mathematics as a symbol of any subject about which a teacher teaches. And that teacher made a mistake in the subject he is teaching. This would only prove teacher is wrong, it would not prove the subject he is teaching is non-existent. Similarly, religions depicted God wrongly. It only means religions are wrong, it doesn’t mean God doesn’t exist!
Congratulations to Vanderhoven7 who got this point with absolute clarity.
God’s non existence cannot be proved because we are all flooded with products, machines, tools, gadgets …. all of which primarily prove someone designed them. If every machine primarily proves someone designed it, then a much more complex, wonderful, and living machine with reproductive feature would mean the same: someone with corresponding ability, of higher energy, designed it because effect explains the cause just like harvest explains the sowing (whether you saw sowing or not).
Even if someone creates a human being in a laboratory taking 94 elements and life-force under the live-telecast all over the world, and explains to us what went into his making this human being, it would still primarily prove he is the designer, and the product is the result of his design.
