Can prayer change God's perfect plan?

[Fake Messiah]

We were in paradise; humanity showed an inclination to believing and following Satan over God; so God sent both Satan and humanity to earth; bashing each other until the hour.

Again, like I said before: If you believe God is omnipotent is it not logical to conclude that he could have made an improved human who still possessed free will - one who was more likely to choose freely the course of good.
And, what about the hundreds of millions of living things that died terrible deaths long before humans appeared on the scene?

Being omnipotent means He has the power to control everything (within His own nature), but that doesn't mean He does.

Yeah this sounds like God from the movie "Oh, God!" played by George Burns where he admits he isn't perfect. He says he would do things differently the next time he creates a universe. For one thing, he would not give the avocado such a large pit.

He chose to create a natural world where things happen as they will.

This is called living in denial.
So malaria virus just happened and we should not blame god? Just like tsunamis that kill hundreds of thousands of people. More than nine million children die each year because of poverty. That's approximately twenty-five thousand each day.
