Are we truly still the same primitive being, or since then have we evolved to something new?
We have evolved, for example we are in process to lose our wisdom teeth (I heard not even half of the people have them anymore), as a result of our jaws shortening.
But all in all we haven't changed much, what changed is culture. Cultural evolution/development can be held responsible for most differences between us and our ancestors, it's seriously outrunning our own evolution. Which means although we are certainly not the same, we are only marginally different.
Are we contemporaries of our brothers, the caveman
Asked like this, I'd say no. 'Contemporary' means lives at the same time as.
This is very true. Most of the large changes in terms of human form are a result of a change in environment, not genetics. For instance, humans in many populations have gotten much taller in the last 500 years, but this does not have much to do with natural selection or even sexual selection (while tall people may be seen as more attractive, short people still are very likely to mate). This, along with increased longevity, has more to do with improved nutrition and medicine.
hmm arn't caveman called : "Homo Habilis"
"Cavemen" isn't exactly a highly specific term.

I agree, the question is worded poorly. A better question is "Are Humans currently evolving in a "meaningful" way?"
We have evolved, for example we are in process to lose our wisdom teeth (I heard not even half of the people have them anymore), as a result of our jaws shortening.
More like 35% of people don't have wisdom teeth. The role that DNA plays in wisdom tooth development is also unclear, and there definitely are some environmental factors at work here. Also, its not like people with wisdom teeth are being selected against enough to make the trait disappear.
we are losing some parts because we no longer need it. we don't need it because we humans have focused ourself on evolving our brain.
That's.... not really how evolution works. You can't focus on evolving your brain, unless you only breed with people with a certain type of brain, or you kill/sterilize those with a certain type of brain. In terms of intelligence, it probably (well, almost definitely) has less to do with brain structure than environmental effects.
But to address the first part of your statement: What are we losing? Why? Is this evolution, or environmental forces?
If it were environmental forces, then it would also be Evolution, due to the environment having a major impact on survival.
The "vestigialization" of our appendix, coccyx, wisdom teeth, ear, face, mandibles, craniums, goosebumps, extra breasts, eyes, or what have you have not been decided on a case-by-case basis.
This post automatically assumes that we believe in cavemen. I, however, don't. There is not enough rock solid proof that they exixted. Look at the Cro-Magnon man and the Java Man. Both presumed cavemen, both proved wrong. Any evidence that cavemen actually exist? I think caveman is something you believe in when you watch looney tunes as a 6 year old. Just like "Santa".

You're going to have to explain why you're not sure how cavemen were around before the rise of civilized tribes/societies. I would like for you to look in this section and even browse the citations given. If there is evidence of Cro-Magnon life, with even their creations left behind, one would think the Cro-Magnons were at least intelligent enough to be cavemen. However, they were more than that. They were semi-nomadic.

Both exist, though the magical representation of Santa does not. Throw in the Easter Bunny, the Tooth Fairy, and religious deities too while you're at it.

Cro-Magnon would still be what we would term a caveman. It's just not a direct descendant. There were other humans running around besides us you know. As for Java Man, the parts came from different species of different eras. Though it's still believed some parts did indeed belong to what we would call a caveman.

There is plenty of fossil evidence someone as closed minded as your self will not see. Not all of it is hoaxed or shown not to be part of our linage.
If it were environmental forces, then it would also be Evolution, due to the environment having a major impact on survival.
Evolution refers specifically to a change of allele frequency over time. We only say that change can be attributed to evolutionary forces if the change can be traced back to a difference in allele frequencies in a population. Environmental forces, which can influence allele frequencies, are not quite so restrictive. As you noted, the environment can affect allele frequencies, but only if it has an effect on which members reproduce, and how much they reproduce. In many populations, I think most humans themselves decide if, and how much, they will reproduce. An example might be: Are Americans so overweight because they have easy access to fatty food, or do they have a genotype that differs significantly from other populations? How is obesity selected for or against?
The answer to such questions is often "both", so we try to determine to what extent each each factor contributes to the total observed change.
There's no evidence for alien DNA in our genome; there's however a whole sh*tload of evidence in favor of migration waves from Africa and possibly even some connections to Neanderthal hominids. Fossils of other hominids make it possible to trace our own evolutionary morphology.
Plus, how could aliens who are so mighty to provoke an impossible flood not have a better method to eradicate humans without needing to eradicate the rest of the fauna/flora?
Actually, I should have started with this question: where did you get that alien hybrid thing from, and what are your supporting evidences?
