I don't debate with creationists online.
I do, but not for the sake of the creationists; hard core creationists, by definition, will not be swayed by logic and reason and facts, so it's generally easier to wait and let natural selection take care of them. I do it, online and in real life, more for the sake of the audience, who are often all too easily seduced by the simple stupidity of creationism; creationism doesn't require people to think, which is hard, just believe, which is easy. This is especially important when the audience is in charge of things like textbook selection etc.
It's a toxic behavior that does nothing good for your psyche, well-being, or mood as a rational, logical person.
I think that depends on how you go about it. If you find yourself getting angry or frustrated, then you should probably stop. However, if you take it less seriously, such as treating it as an opportunity to troll creationists with reality, it can be good mental exercise.
You can quote as much repeatable scientific information as you like, and all they will do is stand there yelling "BIBLE! BIBLE! BIBLE!" at the top of their lungs. We have all the data, supported by centuries of research in myriad cross-connected scientific fields, and all they have is a mis-translated two thousand year old book of folklore.
Which is why I often find it amusing to fight creationism with creationism. I'll sometimes "agree" with them that yes, the world was created by a powerful god. Odin made the world out of the corpse of the giant Ymir. He made the sky out of Ymir's skull. The rivers are made from his veins. His fluffy giant brains became the clouds. Detroit was once Ymir's rectum. "Really it makes a lot of sense when you think about it. And we know it must be true because Odin himself said so as told in the Voluspa of the Elder Edda."
This has a double benefit of really infuriating the creationists while pointing out to onlookers just how damn silly and irrational both myths are when someone tries to pretend they're historical fact.
Approximately sixty years ago we- as a species- made it from the earth to the moon, using only sheer balls and slide rules.
But we didn't do that as a species.
What really happened was a small group of very clever bodgers really, really wanted to put a man on the moon. For reasons. And so they got together with another small group of quite cunning bastards who managed to convince the U.S. government and people that this was the best way to show the Russians that American Dick is bigger than Russian Dick. Oh, and work out and demonstrate the technology to rain destruction down on the Russians from space should they violently disagree.
As a species we just sat and watched the whole thing on television, and most of us didn't even do that. But then that's true for most change, including, to reference a previous topic in this thread, evolution. Innovation almost never comes out of a group as a whole, but almost always from a small sub-group within the general population.
Point blank: Today, RIGHT NOW. Your laptop or cellphone has more than a thousand times the computing power and processing speed of the entire NASA mainframe at the time of the moon landing.
Which isn't entirely relevant because computing power is not what gets people to the moon. Once you've worked out the orbits ahead of time it's almost like chucking a rock. That's why Apollo 13 was probably the most impressive of all the Apollos: shit happened for which they didn't have it all worked out ahead of time and they had to figure things out by the seat of their pants.
And what do we use these powerful devices for? In tota, as a species? Exploring this wonderful universe and all it's beautiful manifestations? Personal growth in the expansions of our minds via co-existence with different cultures? Expanding our understanding of both the finite physical universe and our infinite interactions of the awesome machinery of nature?
Nope.
We look at cat videos, and bitch about restaurants.
Also porn. A LOT of porn. Which always happens with every new technology. People were talking about the possibility of brothels on the moon even before Apollo 11 put a man there.
It's better just to laugh at it.
I mean seriously, their banana argument? Google "artisan banana plants".
Never mind the fact that bananas have been unnaturally selected for human use by human cultivation for millennia. Creationists wouldn't know a wild banana if it bit them on the ass. Not that they would understand that point. I find the best way to deal with the ridiculous banana argument is by scaring the creationists away by putting a condom on it. "See how it was perfectly designed by the creator to demonstrate safe sex in our schools?"
Pfft, that's retarded. Technology is supposed to improve our lives. If it doesn't do that, then it's pointless. Shit like that is like the Burj Khalifa, it's just a dick measuring contest with ourselves with pointless applications of fancy technology.
Until a given piece of technology actually benefits people, it's no better nor worse than cat videos. (Well, except cat videos benefit us now, by being entertaining.)
Well despite what I said above about dick measuring, the Apollo Project and the Space Race in general did actually benefit people, though largely through intangibles and side benefits (it also did a LOT to stabilize the Cold War which was a hell of a good thing). For example: without the heavy lift, high orbit technology developed for Apollo, geostationary orbits would not be achievable. That means no geostationary communications satellites, which mean no satellite television, which means no 24/7 satellite television porno channels (I'm assuming those are a thing - probably a safe assumption). The great benefit of 24/7 porno channels that that they keep the sort of people who would watch 24/7 porno (mostly teenagers) occupied. Otherwise those people might leave their homes to find other ways to occupy themselves, and nobody really wants that.
Also the poor Canadians would be stuck with nothing but Canadian broadcasting if they couldn't sneak across the border to buy U.S. mini-dish receivers. And you can forget satellite internet, GPS, decent weather forecasting, and so on and on with other things that benefit us on a daily basis (which a lot of young people these days seem to take for granted).
As to the intangibles, well Apollo was a huge step forward in manned space exploration, even though we've done fuck all in that direction since. And that's probably the most important thing it did, because it helps give humanity the most important benefit of all: a future. I know this might sound sappy in these cynical, jaded times, but it's still true. In the long term, humanity's future is Out There, because if it isn't, well then we don't have a future.
Extinction is for chumps.
