Could the Human Race really be the Aliens on this planet??

Right.  The process isn't random and the mutations are.

It doesn't seem unlikely at all, at least to me.  It's just a problem of scales.  Humans live about 100 years at best.  Our scale of time is years.  All of recorded history is a sliver of time on earth that is beyond insignificant. 

When you can thing of time on a grander scale, it's not really hard to believe that things could change that much.  Assuming you accept that genes change over time, and really try to imagine billions of years, it doesn't only seem likely but inevitable.

I just can't see how, under any period of time, and any circumstances, that bacteria could eventuallt transform into a human

Can you imagine that in 1 million years, a one celled bacteria could become a two celled organism?

Can you imagine 1 million years later that two celled organism becomes a 4 celled organism?

Can you imagine in another million years that four celled organism can become an 8 celled organism?

Can you imagine in another million years that 8 celled orgamism becomes a 16 celled organism, and that some of the cells begin to perform different tasks?

Can you imagine that in another million years, we have a 32 celled organism with several different specialized cells?

Obviously, this is just a hypothetical, but that's 5 million years. Is it that hard to imagine going from 1 to 32 cells in that time?  Five million years is less than .1% of the time life has existed, as far as we know.  If you can believe that much change can happen in such a relatively small amount of time, is it hard for you to believe that in more than 1000 times that amount of time we can get to organisms like mammals?
