The "Solutrean hypothesis" has been floating around for a while, and evidence keeps accumulating.  A very nice Solutrean spearhead was recovered from East coast waters by a fishing boat just recently.

John, this is not a new theory  
It all begun when some archaeologists found votive stone hoards in North America that are 100% similar to some Northern Spain-South France ones.
I mean purposely broken bifaces and stuff like this. The theory (which I agree with) is that during the last Ice Age (20-19'000 years b.C.) North America and Spain/France were linked by an ice crost, and that these early Europeans crossed it.
The biggest flawl is the reason why some people should travel across a huge glacier!

My people's ancestors(first people to come to America) had french style stone tools,  guess it was the hottest thing back then kinda like the latest technology nd stuff.

Not sure,  but I guess it was before there was distinct peoples,  before they broke up into different indigenous peoples.  But when they came to Alaska they found out that there wasnt as many knapping materials so most had to adapt.

"Tell me why we're doing this again?"
"I told you, it's because of that big piece of ice"
"What's that gotta do with anything?"
"Well it's there so we might as well use it...."

You have to be careful about the European flint tools, quite a few came over as ballast in the holds of ships.   From the period of 1500 to about 1600, the NA were still making knapped stone tools and they also used the flint that European ships dropped.  
 
Even today, knappers such as Luke Webb pick up those ballast stones and make tools from them.

Yes, archaologists have to be careful.... I recall speculation that the Chinese had reached the West coast of the Americas in ancient times....Based on Chinese "Junk" anchor stones found in places like San Francisco Bay.
However, it was then found that Chinese vessels used these ancient stones for ballast, hundreds of years later in contemporary times.
The Nat Geo show mentioned a number of "waves" of migration of Siberian peoples across the land-bridge of the Bering straits area.    
They have identified at least three, leading to the minor genetic/ethnic variances between Amerind peoples.
It's also possible that some South American indegenes had yet different origins.... But that's very speculative.

The peoples that crossed that Bering-Strait land bridge (or ice bridge!) were of different ethnicity than the putative "European" peoples who we call the Solutrean culture.  
There are some anthropologists who think these people might have become the "Clovis" culture, because their stone tools were similar to the Clovis tools.
The Clovis were kind of the high-point of stone-age culture as far as their tool kit; they made very finely-crafted stone tools indeed.
The Solutrean items are of similar design, but not as refined.

That might not work, c_a.  When the ocean freezes it's not like a lake or river.  There are huge blocks tossed up everywhere.  The going is very difficult and probably impossible for an ice boat.

Most early drawing of Native Americans look much more European than the guy on the U.S. Nickle.

Like strapping humans to the tip of a bomb and shooting them into space????

Here's what I've uncovered about this subject. I've spoken to several archaeologists and professors, and they all seem to think that there is ample evidence to support a prehistoric migration from Europe to North America. All evidence from the earliest sites discovered so far over here point to European origin. They can see no reason to argue against a theory that early Europeans weren't able to move along the ice shelf and finally find landfall on the east coast of North America. These people were well versed in maritime survival...meaning fishing and hunting aquatic animals, and it wouldn't have been too hard on them to just keep moving west.  
 
Interestingly, I have discovered that the current theory of the Asiatic exploitation of North America is driven more by politics and public funding than by true scientific fact. Apparently, a certain ethnic group has discovered that if they can portray themselves as being the "true" natives who were savagely decimated at the hands of European colonists, they can now receive certain benefits and and government subsidies. This group has somehow managed to get the ear of the government over here and the situation has gotten to the point that they can say who is "native" and who isn't.  Here's and example...let's say you and I are out on a dig and discover human remains...very old human remains. Being law abiding citizens, we report this to the local authorities. It is determined that these remains are distinctly European...yet they are 20,000 years old. What do you think will happen??? Here's what will happen. The local Indian tribe will lay claim to them and confiscate them as their own. If I was to ask them to prove that those remains were actually their ancestor, I would be committing a federal crime...just for demanding proof. Because of the current laws, I would not be able to conduct any scientific study of the remains and would have to hand them over to whatever "native tribe" laid claim to them...even if I discovered them in Kentucky and the tribe that claimed them was in Alaska!!!. Do you see what's going on??? Unfortunately...every set of human remains over here older than 500 years old has been legislated as "native"...meaning Indian...and are subject to the disposal of the tribes at their whim.
 
Fortunately for science there are still several scientists that will not succumb to politics at the expense of fact and are sticking their necks out to get to the truth. I applaud these folks for their tenacity and hope one day they will be heard.
