So, now you see why God placed cancer into the design. He never meant us to be unhealthy. He always wanted us to use the benefits of cancer to enhance our lives.
What are the benefits of cancer? How can your life be enhanced by cancer? Career in drug testing? What did your God smoke when he put cancer into his 'design'? Must be some good stuff.
PS. If you were in a courtroom and a witness claimed that he saw a witch flying on a broomstick above Manhattan, and no traffic cameras recorded it, would you believe him? That is why I do not believe Bible 'eye witnesses', God included. Talking snakes? Please, don't waste my time.
But if many people saw many witches, you might at least question your belief a little. That's why the Bible is as big as it is, with as many witnesses and writers as there are. To give you an opportunity to question your false beliefs, so that you might have the chance to be saved.
You didn't look at the major benefit of cancer? You didn't look at what trophoblast does in the human system? When the embryo comes out of the fallopian tube into the uterus, it has to find a way to attach to the uterine wall. Part of the embryo becomes cancerous, and eats into the uterus. Then, at just the right time, the pancreas of the new fetus becomes active, and controls the cancer, turning it into the placenta.
In other words, without cancer, there wouldn't be any mammalian life on earth, and maybe no life at all.
The answer about cancer I just gave you is very simple. Yet it is way more complex than something as simple as "yes" or "no." Forget your simple y or n answer. Look at the answer that I gave, and realize that the universe is complex beyond belief. That's why Jesus did the difficult work for us, because we couldn't do it for ourselves because of the complexity involved. Because of Jesus, the only thing we need to do is believe.
''Every sixth death in the world is due to cancer, making it the second leading cause of death (second only to cardiovascular diseases'' Whether ''cancer'' helps at first is meaningless if it's going to kill you later randomly. Not to mention the ton of flaws in the human body.
God gave mankind the freedom to do all kinds of things. The fact that mankind decided to use their freedom to corrupt God's creation for them, doesn't have anything to do with God.
In fact, God has gone about saving people through Jesus salvation. Such still doesn't force any people back into perfection. Many of them still corrupt God's creation, and ignore God's salvation.
Part of your personal desire for flaws is that you would deny God rather than see His salvation for yourself. You are doing it, not God.
