Can every single thing be attributed to intelligent design?

Everything has a cause except the uncaused caused.

Yes . It is all designed so God could have His own Growing-up Place in order to ( be forced ) learn to love everyone unconditionally . And He knew that all of the rest of the Bored Cherubs would beg to come in , even after His warning them that they'd have to wear a God-Body as He , which is geared to have to become perfect ; or else they'd subconsciously punish themselves severely enough in order to motivate themselves to get back on the path .

If you believe the fantasy.

Nothing can be attributed to 'ID', It is total BS that is only believed in by backward idiots.

No. Nothing about this universe was intelligent ly designed.

"what else couod have been ? god!" no, thats not how you answer.

Bacteria is necessary to sustain life. It can also kill if not managed. Accordingly, God tells us that this is our natural world to manage and sustain. It takes time to learn how. DYING is part of this natural world. It applies to everything that lives. God's job is primarily in heaven. Don't treat this concept of heaven as meaningless.

If you think so then, yes.

Else no.

As long as you have no testable evidence, it makes no difference and you can make it up as you go along.

What we now call killer bacteria and fatal disease would not be a killer bacteria or fatal in the least if our bodies were 10 times stronger and healthier than they are now. You could get bit in the neck by a rabid dog and not catch the disease. Man was once much more healthy than he is now. Just 5000 years ago there are stories in the Bible about men who ran from one city to another city and back for sundown total of 40 miles in order to do this the person would have had to be able to run at 5 miles an hour for a solid 8 hours. The Bible documents the lifespan dropping from a thousand years down to only a hundred years and it names the people as the ages slowly get less and less. Killer diseases back then we're minor nuisances to those people no more than a little cold.

no the killer bacteria would be from Satan messing something up. GOD DESIGNED THE TREES, OCEANS, ANGELS , HUMANS etc.
