Ken Ham, the creationist behind the giant Noah's Ark replica nearing completion in Kentucky, received some pointed questions on Twitter from those who have a problem with the central message in the biblical story.

The Noah tale, which is in the Genesis, involves a massive global flood that wipes out the entire human race save for eight people -- and that doesn't sit right with some:

@aigkenham If someone kills 99 people but lets one go because he decided they weren't so bad he's not a saviour, he's a serial killer — Scott Johnson (@scottiej24) April 25, 2016

@aigkenham

Genocide had never been more popular — Total OneEighty (@Total_180) April 27, 2016

Ham, who debated evolution with Bill Nye the Science Guy in 2014, engaged in what seemed like a debate with all of Twitter over the issue.

He fired off a series of tweets explaining not only why God killed off much of the world's population, but also how it's not his fault he had to wipe out everyone.

It was ours. Here's a sampling:

Secularists emphasize God's judgment at the Flood of Noah's day but ignore man's wickedness and why a righteous God had every right to judge — Ken Ham (@aigkenham) April 25, 2016

Secularists accuse God of being immoral as He judged at the Flood but ignore the fact they've no absolute basis to make any moral judgment — Ken Ham (@aigkenham) April 25, 2016

Secularists mock at @ArkEncounter because they want to suppress the wickedness of man and that we're all under judgment by a Holy God — Ken Ham (@aigkenham) April 25, 2016

Secularists mock those who trust God because of death & suffering we see-cause they refuse to acknowledge death's a consequence of our sin — Ken Ham (@aigkenham) April 25, 2016

Death, suffering and disease are not God's fault, they're our fault because we sinned against a Holy God who is the righteous God — Ken Ham (@aigkenham) April 25, 2016

For evolutionists, death & suffering & disease is normal—for Christians death is an enemy, an intrusion because of our sin — Ken Ham (@aigkenham) April 26, 2016

Many responded to Ham as he sent out his tweets -- with some mocking the ark and the very unbiblical way in which it's being built:

Silly @aigkenham! Real ark was built by rock monsters. Haven't you seen #noahmovie? — Scott Chase (@ScottChaseBU) April 27, 2016

The Ark Encounter is set to open this summer in Williamstown, Kentucky.

In other ark news, a second massive replica is expected to sail across the Atlantic this summer.
