He's not saying anything in them that he hasn't said before, he calls evolution a lie and says that creationists don't need scientific proof because... well... the bible says you don't!
Of course the authority he's quoting is Romans 1 which actually says:
The wrath of God is being revealed from heaven against all the godlessness and wickedness of people, who suppress the truth by their wickedness, since what may be known about God is plain to them, because God has made it plain to them. For since the creation of the world God’s invisible qualities—his eternal power and divine nature—have been clearly seen, being understood from what has been made, so that people are without excuse.
Can't see the hand of god in all creation? Wrong! Of course you can, and if you say you can't you're lying! Says so right there in black and white "...suppress the truth by their wickedness..." See? you're not only lying you're wicked too.
This has been Ken's fall back for ages, he pulls it out whenever the mountain of evidence against biblical creation become too great for even his tenuous hold on reality to ignore.
First Ken makes the best case he can by using outdated science and bad logic, and when it fails he claims that evidence isn't needed, and in fact could never prove creation over evolution... Wait what? This man runs a website called "Answers in Genesis" whose sole purpose seems to be to hold up examples of validating the bible as literal fact. He even started a "Creation Museum" to show how he can make it all look so scientific and rational...
In legal terms this is called a "double plea" or sometimes "duplicity" (does that sound like a good word kiddies?). It's a bit like saying "I didn't shoot that man... and if I did then it was self defence".
When I get upset at people of faith it's normally because of the harm they do to others and Ken Ham is a very harmful person. He perpetuates claims he knows are not true, and encourages people to teach these same mistruths to their children. He even discourages teaching children skills like logic and critical thinking because they might one day lead to people spotting the lies.
PS: Ken keeps throwing Romans up as his example that you don't need evidence for god, but thats not what it says. What it does talk about is that when people don't believe in god, they create their own gods and then it's just a short step to unnatural acts with animals (I'm not kidding, read the whole thing and you'll see).
