I don't know where you come up with the statement that earth formed from a supernova. That is nonsense. It is theorized that all elements above iron in the periodic table were created in supernova, so maybe that is where that comes from.
For the heat, some residual from the formation of the earth, some from radioactivity.
The dynamo effect arises from the motion of iron atoms in the molten core, driven by convection currents which result from the heat. The PBS/Nova article explains it all. You don't seem able to comprehend it.
That list is a pile of BS. You want Creationism taught? Do it in Bible school where it belongs.
ChesBayJJ I given you a chance to explain instead of posting links from NOVA and I think you're not very educated. You're also very ignorant.
The secular scientists I know all believe earth and the solar system were formed from a supernova explosion. Let Stephen Hawking explain. I use him as the standard for BBT and solar system formations.
And your dynamo explanation is lacking. It just goes to show that you're a lemming and just read basic science articles. Most of it was debunked around 2011. Why don't you learn about the SWARM satellites and how it was sent up to learn more about Earth's magnetic field. They are today backing up what I stated months ago about moon's gravity causing the tidal action to generate the magnetic field. At least, you didn't mention the pole reversal which is another error by the lemming atheist scientists. How do I know about these things before the atheist scientists finally find out the truth? I read the Bible, learn about creation science and am intelligent enough to figure how gravity affects us all and figure it out.
For aliens, the argument I use is Fermi's Paradox. It still has held up and is observable science. It's like my science is correct and true until you find life outside of earth (unless it's by panspermia). So far, you are wrong and I think you will be until our universe comes to an end. Sir Isaac Newton predicted it could come in 2060. Who knows? God stated that he's not going to tell us the beginning nor the end, so that is something we won't know until it happens.
As for the rest, you should be the one to read and learn, but I doubt you will. Like I said, you're not very educated.
