Bhumi is the coat the dress of Atman so if all sentient beings are born. How did Atman become a jiva Atman ?
What you have written in the body of the question isn't making much sense to me :). Probably you may want to add some more stuffs to the body so as to make it more clear.
For the question in the title though the following is an answer:
From Maya everything is created. Even Bhumi or Earth is the product of Maya. So, Bhumi being a product of Maya can not be Maya itself/herself.
From Maya actually the three Gunas (Sattva, Rajas and Tamas) are born. So, in that way Maya becomes the creator of everything because everything is formed of the three Gunas.
See the following passage:
21-23. O Dvaipâyana! Thus saying, Visnu stopped. I was greatly astonished and asked that Eternal Vâsudeva, the Deva of the Devas, the Lord of the World, “O Lord of Ramâ! What is the form of Mâyâ? How is She? What is the measure of Her strength? Where She resides? Whose substratum is She? Kindly tell these to me. O Preserver of the Universe! I am greatly desirous to see Mâyâ; Shew Her to me quickly. O Lord of Ramâ! I am very eager to know Mâyâ. Be graciously pleased to describe tome the glory of Mâyâ.” 24-36. Visnu said :-- Mâyâ resides everywhere throughout this whole Universe; Her nature consists of the three Gunas; She is the substratum of all; She is omniscient, and acknowledged by all; invisible, and of diverse forms.
. Nârada said :-- O Thou whose only wealth consists in asceticism! I am now describing to you all those good stories; hear attentively. O Muni! This Mâyâ and Her Power are incomprehensible even by those who are the foremost amongst the Yogins. This whole Universe, moving and non-moving, from Brahmâ to the blade of grass, is enchanted by that Unborn and Incomprehensible Mâyâ; therefore no one can escape from the hands of that Mâyâ.
Devi Bhagavatam Book 6, Chapter 28.
Note that here Maya is stated to be unborn but the same can not be said of Bhumi or Earth. Because Earth came into existence at some point in time. It was of course not existing eternally.
So, Maya and Bhumi are not the same. Although to say that Bhumi or Earth is an aspect of Maya is alright. Furthermore, that Earth is a highly praised Vedic deity is also true.
