We don't know what it means to be like God, except that it is a glorious thing. Our belief is comparable in some ways to the traditional Orthodox belief in theosis. We know even less about what it means to have "a continuation of the seeds forever" (D&C 132:19). Most of us are satisfied to live with "I don't know" as the answer to what it means to become like God and to have an eternal family.
I've done no empirical survey, but my impression is that there may be Mormons who understand themselves to be ultimately the creator of a world, but it isn't a standard, common belief. It is more something left over from the 19th century. Few of us deny that belief, but few of us assert it either. Most of us stick with not knowing. Most of us are satisfied to believe "that same sociality which exists among us here will exist among us there, only it will be coupled with eternal glory" (D&C 130:2), and with not knowing the details of what that means.
As a Mormon not unlike lots of other Mormons, it is important to me to acknowledge the sacrifice that Jesus made for me and all other persons, and I must actively remember that he is our Messiah. I must pray often and read the scriptures. It is important to perform the service to which I have been called in my congregation. It is important that I take part in our monthly fast and, as part of my fast, make a generous donation for those in need. I need to live with my wife, children, and grandchildren in love. And it is important that the love I learn in my family go beyond its boundaries to my congregation, to other LDS congregations, to those of whatever religion, to all of humanity.
The sacred garments I wear remind me of those obligations more than they remind me of doctrines. What it means to become like God remains a mystery about which I don't think very much. Whatever it means will work itself out in my understanding in the eternities and has little to do with what it means to be a Mormon now, in the life I am presently living.
