CODE:

SPSecurity.RunWithElevatedPrivileges(delegate()
{
using (SPSite site = new SPSite(strSiteUrl))
{
site.AllowUnsafeUpdates = true;

HttpContext oldContext = HttpContext.Current;
SPServiceContext context = SPServiceContext.GetContext(site);
HttpContext.Current = null;
UserProfileManager currentUserProfileManager = new UserProfileManager(context);
bool userexist = false;
try
{
user = currentUserProfileManager.GetUserProfile(accountName);
userexist = true;
}
catch (Exception ex)
{
userexist = false;

}

 if (currentUserProfileManager != null)

if (!userexist)
{
try
{
user = currentUserProfileManager.CreateUserProfile(accountName);
}
catch (Exception ex)
{
throw;
}
}
}
}
}

I think that it is impossible to create a user using sharepoint tools. You need to first create an account in AD using, for example, this: https://www.codeproject.com/Articles/90142/Everything-in-Active-Directory-via-C-NET-Using

And only then set up replication of profiles in the sharepoint
