Does a state called "Antarabhava" an existence between death and rebirth exist?
Traditional Theravada sources, highly respected scholars and texts in Abhidhamma directly decline this as there is no such thing in the Dependant Origination. Arahat Moggaliputta Tissa Thero has also rejected this in the 3rd Buddhist Council.
Bhikkus who support the claim that "Antarabhava" exists takes examples from suttas such as Tirokudda Sutta the first few verses, Kutuhalasala Sutta the last paragraph where Buddha states that a being who has left the present body but has not reborn in another body is sustained on craving (Tanha).
